19b718fe73 Pass undefined to JS builtins when called with implicit receiver. 
A couple of corner cases have to be treated specially to not break
everything: eval and getter/setter definitions.

68e2d1bfed Do not allow inlining functions with direct arguments access. 
Our implementations of arguments without materializing the arguments
object (based on inspecting the stack frame) does not work for inlined
functions.  Guard all attempts by disallowing them if possible or else
bailing out of the optimizing compiler.

64c610727d MIPS: Added the stop() instruction with same behavior as on Arm simulator. 
The already working watchpoint break mechanism has been extended to handle "stop" instructions, with text messages.

Explanation (also in constants-mips.h):
On MIPS Simulator breakpoints can have different codes:
- Breaks between 0 and kMaxWatchpointCode are treated as simple watchpoints, the simulator will run through them and print the registers.
- Breaks between kMaxWatchpointCode and kMaxStopCode are treated as stop() instructions (see Assembler::stop()).
- Breaks larger than kMaxStopCode are simple breaks, dropping you into the debugger.

The current values are 31 for kMaxWatchpointCode and 127 for kMaxStopCode.
From the user's point of view this works the same way as the ARM stop instruction except for the break code usage detailed above.

b92ef0be32 MIPS: port Fix calls of strict mode function with an implicit receiver. 
Port of r8040 to mips.

Original commit message:
Strict mode functions are to get 'undefined' as the receiver when
called with an implicit receiver. Modes are bad! It forces us to have
checks on all function calls.
This change attempts to limit the cost by passing information about
whether or not a call is with an implicit or explicit receiver in ecx
as part of the calling convention. The cost is setting ecx on all
calls and checking ecx on entry to strict mode functions.
Implicit/explicit receiver state has to be maintained by ICs. Various
stubs have to not clobber ecx or save and restore it.
CallFunction stub needs to check if the receiver is implicit when it
doesn't know from the context.

3c7e1d7015 Create stand-alone json parser (including scanner). 
The current json parser and scanner inherits fromt he normal scanners and parsers,
which are more complicated than we need for parsing json.

The supplied scanner works directly on the string supplied and has a
fast case mode for scanning only ascii characters (it will simply
create a substring or a symbol directly from the existing string). To
allow for creating symbols from a substring I have added a
SubStringAsciiSymbolKey that creates the hash based from our string
without extracting the sub-string. In case we need to add the symbol
it simply creates the symbol directly from the characters inside the
given string.

a1bcafab69 Improve bit tests on IA32. 
Bit tests with a memory operand should be avoided on Intel processors.
On Atom bts with a memory operand has 10~11 cycles latency and on Core 2
it has 5~6 cycles latency, and also produces multiple uops.
If the bit base operand is a register the latency is 1 cycle instead.
This CL improves several cases from Kraken 1.1 benchmark on Atom. For example,
12% for imaging-desaturate, 8% for audio-fft, and 5% for audio-beat-detection.

f19fb45510 MIPS: Minor fixes to simulator and builtins-mips. 
Updated to include fixes to several mips arch-specific files, corresponding to recent changes in r7944, r7935, r7926, r7914, r7910, r7895, and parts of r7423, which had previously been missed for mips. Rebased on r7964.

The simulator changes were missed on r7893 for code-stubs-mips,
where the DirectCEntry stuff was added.

There are also a couple small changes to builtins-mips following
r7879 for the other architectures.

When the stub return a heap number we do a state transition to

There is room for further improvement in the typefeedback for the
case of -0. This change however does not address this and only fixes
the acute issue.

123500999f Reland 7917: 
Better support for 'polymorphic' JS and external arrays

Allow  keyed store/load stubs to switch between external array and fast JS arrays without forcing a state transition to the generic stub.

There CL consists of two pieces of functionality. First, code stubs for fast element arrays don't immediately transition to the MEGAMORPHIC state when there's a map mismatch. Second, two ICs are cached per map for fast elements, the MONOMORPHIC version, and a new MEGAMORPHIC version that handles two or more different maps and dispatches to shared stubs to perform the array operation.

f39b0dfccb Handle all kind of arguments in the ToBooleanStub. While this is not very thrilling in itself, it is one of several steps to add type recording to this stub. Removed a duplicate check for null in the ARM stub and made a tiny simplification, removing a sub instruction. 
As a side note, this change has some positive impact on the performace, e.g. imaging-darkroom is 8.3% faster and ws-ieee754conv is even 19.9% faster. No idea why the speedup is so big in some cases, but never look a gift horse in the mouth... ;-)

e14402b1df A first skeleton for introducing Harmony proxies. 
1) Add new type JSProxy for representing proxy objects.
   Currently devoid of functionality, i.e., all properties are undefined.

2) Some rudimentary global $Proxy functions to create proxies.

Next step: Hook up getProperty and getOwnProperty handlers. Will probably
require introducing a new LookupResult type, which is a mixture of
INTERCEPTOR (handles any property) and CALLBACK (calls back to JS).
Can we unify this somehow?

TODO: Should probably rename existing Proxy type to something like
"Foreign", to avoid confusion.

If a HDeoptimize does not cut away parts of the control-flow-graph
we don't need to insert uses to correctly elimiate dead phis since
the full function is visible to the optimizing compiler.

This is a small improvement of the change r7221 which fixed a problem
when deoptimizing on never executed case-clauses.

4e18d50834 Add constant splitting for user controlled constants in the full compiler 
This is IA32 only for now.

Added a random value to each assembler instance (JIT cookie) to be used for constant splitting. Added safe versions of setting a register with an immediate value and for pushing an immediate value. Used these functions where user controlled immediate values could be emitted in the code stream. I also used it for immediates which are an argument number even though the number of formal arguments is currently limited to 16k.

I found no compares directly with user controlled constants.

I am not sure whether the test is that useful, but it might catch some changes missing constant splitting.

c10267f1fa Refactor HCheckInstanceType to allow mask/tag tests. 
This allows us to get rid of totally fake LAST_STRING_TYPE and makes
it possible to test for symbols.

I considered splitting HCheckInstanceType into two instructions, but
it seems nice to be able to hide the instance type implementation
details from the hydrogen level.

4912c0371b A few "extract method" refactorings, trying to get individual method definitions 
onto a sinlge 30" screen. A lot of times, the AST visitor stops a bit too early,
so we have to do the rest of the dispatch by hand. This is caused by the fact
that the kind of the AST nodes are a bit too coarse for some traversals (e.g. a
single node type for all binary ops), perhaps one could try to refine this a
little bit more.

45d07bcd32 Simple elimination of redundant array-hole checks. 
If the result of an fast elements load is converted to an untagged
representation we can omit the hole check if the value is not used
anywhere else except for HChange instructions converting it to
an untagged representation since those will deoptimize for the hole
value anyway.

5b2e2636b7 Faster string equals in generated code. 
In my previous change I mixed up "compare" and "equals". This made us
miss the fast length check before comparing strings for equality.

Now we have a separate helper for "equals". It shares some of the
inner loop details with "compare". I'll see if this can be cleaned up
without making it unreadable.

5a9fa7a8c6 Change v8Locale to match proposal - constructor is different (takes settings object, not a plain string) and I've added derive method to it. 
Added comments to i18n.js methods and properties, and util functions to check settings and locale validity.

Added LanguageMatcher class until ICU gets C implementation (in progress, but late for our current deadline). I added TODO to remove LanguageMatcher code.

2b730c2bf6 Don't exchange null and undefined with the global object in function.prototype.{call, apply} for natives. 
This makes us compatible with firefox in throwing an exception when
call is invoked on a builtin with null as the this argument.

5197bff4f2 Unified CallWrapper and PostCallGenerator classes, the former is a 
generalization of the latter. This makes CallWrapper architecture-independant,
so it can be pulled up into assembler.h, nuking 3 copy-n-paste classes. Only a
small improvement, but nevertheless...

3e94ac952d Change heuristics for deciding phi-representation types to use int32 more frequently. 
Until now we conservatively chose a double representation if
at least one use occurs in a double operation. This causes performance
degradation in many cases where there are mixes uses (integer and double)

e.g.:

for (int i = 0; i < 10; i++) {
  var t = i / 3.5;
  a[i] = t;
}

where the use in i/3 requires a double, where as the keyed store requires i
as an integer.

For these cases we want to have i as an integer and convert it only before the
double division.

In order to avoid unconditional deoptimization in some rare cases, we check
phis if there is any conversion that will always fail when converting a
heap-number constant to int32.

01707c7106 ARM: Changed the handling of compiletime CPU feature detection 
Always use CpuFeaturesImpliedByCompiler() when selecting CPU features. This checks both for CAN_USE_ARMV7_INSTRUCTIONS and CAN_USE_VFP_INSTRUCTIONS and for GCC preprocessor symbols. This will support using the CAN_USE_XXX for a simulator build used for generating a snapshot followed by a crosscompile using -march= and -mfpu= for selecting the (minimal) target device CPU features. The snapshot will use instructions based on the CAN_USE_XXX whereas the target will at least use features based on both CAN_USE_XXX and -march= and -mfpu=, but will try runtime CPU feature detection a well looking for somethis better.

Remove the compiler based CPU feature detection from the OS::CpuFeaturesImpliedByPlatform() as it did not belong there. Also was already in the CpuFeaturesImpliedByCompiler().

Add the variable 'v8_can_use_vfp_instructions' to the GYP file which can be used to turn on CAN_USE_VFP_INSTRUCTIONS when building V8. I did not add any -mfpu= cflags for this, as there are several options here (e.g. vfp and neon).
