f14b93a508 Regexp: Improve the speed that we scan for an initial point where a non-anchored 
regexp can match by using a Boyer-Moore-like table.  This is done by identifying
non-greedy non-capturing loops in the nodes that eat any character one at a time.
For example in the middle of the regexp /foo[\s\S]*?bar/ we find such a loop.
There is also such a loop implicitly inserted at the start of any non-anchored
regexp.

When we have found such a loop we look ahead in the nodes to find the set of
characters that can come at given distances.  For example for the regexp
/.?foo/ we know that there are at least 3 characters ahead of us, and the sets
of characters that can occur are [any, [f, o], [o]].  We find a range in the
lookahead info where the set of characters is reasonably constrained.  In our
example this is from index 1 to 2 (0 is not constrained).  We can now look 3
characters ahead and if we don't find one of [f, o] (the union of [f, o] and
[o]) then we can skip forwards by the range size (in this case 2).

For Unicode input strings we do the same, but modulo 128.

We also look at the first string fed to the regexp and use that to get a hint
of the character frequencies in the inputs.  This affects the assessment of
whether the set of characters is 'reasonably constrained'.

We still have the old lookahead mechanism, which uses a wide load of multiple
characters followed by a mask and compare to determine whether a match is
possible at this point.

f00631b710 Reduce initial boot-up memory use. This is an other attempt at what 
http://codereview.chromium.org/9179012 was trying to achieve.  This
time I am going for 80% of the benefit with around 5% of the complexity.

It works by reducing the size of the first page in each space.  Unlike the
previous change there is no attempt to grow pages, we just allocate more
full-sized pages when we need more memory.  For this reason the first pages are
not quite as small (compare
http://codereview.chromium.org/9179012/diff/1/src/snapshot.h with the changes
in spaces.cc in this cl):  We want to be able to do a little bit of allocation
before we have to add a full-sized page to the space.

The [[Extensible]] property prevented the very first hidden property
from being added. If any hidden property was added to the object before
preventing extension, adding subsequent hidden properties would have

79a98de9f7 Fix declarations escaping global strict eval. 
According to ES5 10.4.2(3), eval calls of strict code always require
their own lexical and variable environment. For now we just add a new
scope when we parse the strict mode directive. The clean solution would
be to always have this sope present (even for global eval calls) and
adapt variable binding to cope with that.

7d6fd56fd5 Ensure there is a smi check of the receiver for global load and call ICs. 
There was a comment that, for such ICs specialized to the global object,
they were always contextual loads.  This is very brittle.  It is a
micro-optimization that relies too much on the way that things happen to
work today.

Instead, never omit the smi check because it's safer.

448b620dad Basic interface inference for modules. 
All module expressions, and all variables that might refer to modules,
are assigned interfaces (module types) that are resolved using
unification. This is necessary to deal with the highly recursive
nature of ES6 modules, which does not allow any kind of bottom-up
strategy for resolving module names and paths.

Error messages are rudimental right now. Probably need to track
more information to make them nicer.

1729e3c0dd Make the runtime entry for setting/changing accessors "atomic". 
Previously, there were 1 or 2 calls to the runtime when accessors were changed
or set. This doesn't really work well with property attributes, leading to some
hacks and complicates things even further when trying to share maps in presence
of accessors. Therefore, the runtime entry now takes the full triple (getter,
setter, attributes), where the getter and/or the setter can be null in case they
shouldn't be changed.

For now, we do basically the same on the native side as we did before on the
JavaScript side, but this will change in future CLs, the current CL is already
large enough.

Note that object literals with a getter and a setter for the same property still
do 2 calls, but this is a little bit more tricky to fix and will be handled in a
separate CL.

1a356cff3e Fix redefinition of aliased elements in arguments. 
This refactors the way we (re)define elements to perform normalization
and attribute updating at a much deeper level, thereby removing some
bogus special cases in upper runtime layers.

Most element setters take an indicator flag that distinguishes between
setting and defining. Setting of an element causes attributes to remain
unchanged, writability to be checked and callbacks to be called.
Defining of an element causes attributes to be updated and callbacks to
be overridden. The same approach could be taken for properties.

6703dddac4 Support fast case for-in in Crankshaft. 
Only JSObject enumerables with enum cache (fast case properties, no interceptors, no enumerable properties on the prototype) are supported.

HLoadKeyedGeneric with keys produced by for-in enumeration are recognized and rewritten into direct property load by index. For this enum-cache was extended to store property indices in a separate array (see handles.cc).

New hydrogen instructions:

- HForInPrepareMap: checks for-in fast case preconditions and returns map that contains enum-cache;
- HForInCacheArray: extracts enum-cache array from the map;
- HCheckMapValue: map check with HValue map instead of immediate;
- HLoadFieldByIndex: load fast property by it's index, positive indexes denote in-object properties, negative - out of object properties;

Changed hydrogen instructions:

- HLoadKeyedFastElement: added hole check suppression for loads from internal FixedArrays that are knows to have no holes inside.

1336b913d0 Make built-ins strict mode conforming, and support a --use-strict flag. 
* Turned all uses of 'const' into 'var'.
* Turned all uses of local 'function' into 'var'.
* Added a couple of missing toplevel 'var' declarations.

One consequence is that the properties on the builtin object  are no longer
non-writable, and I had to adapt one test. Is that a problem?

Unfortunately, we cannot actually switch the library scripts to strict mode
by default, because that makes observable things like poisoned .caller properties
for library functions.

Also removed dead flag code in Compiler::Compile.

1dd2b094a5 Implement fast literal support in Crankshaft. 
This extends the current support for nested object literals we already
have in Crankshaft, to also support nested array literals and mixed
nested literals containing arrays and objects. All three types are
generated by the unified HFastLiteral instruction.

All previous upper bounds on nested literal graphs remain unchanged,
keeping the size of generated code in check.

The main intention is to boost performance of two-dimensional array
literals containing constant elements (aka. matrices).

8a7f1568c4 Ensure that we do a non-incremental GC before relying on weak handle callbacks. 
Previously, some tests failed when being run with a low GC interval. This was
caused by a switch of the GC to incremental marking mode, which in turn did not
fire any callbacks for weak global handles. Now we make sure that we run in
non-incremental mode, although via a slightly misleading GC flag.

We should probably review the uses of PerformScavenge() and gc() in our tests to
see if they actually mean "make sure our callbacks fired".

b8b50400d2 Inline builtin Math functions functions in more cases. 
Until now we only could inline as specialized HIR instructions when called
as a method (e.g. Math.abs)

It is very common practice to abbreviate calls to those functions by defining
a global or local variable like:

var a = Math.abs;
var x = a(123);

This change allows inlining them when called as a function (global or local).

dc3f16a321 I will apply it to the nodes that can't be mapped to Heap object or Native object. 
As example there are 'Detached DOM Tree' nodes in WebKit. It is very useful to be able to see all such
nodes grouped together. It can be done with help of some post processing but I did this explicitly
on v8 side because it is much faster. At the moment this kind of nodes has kNative type.
I'd like to hide these nodes from the Retainment View but I can filter them only by name.

07d720ec41 Detailed heap snapshot usability improvement. 
The detailed heap snapshot has two groups of nodes. The first one
is the group for v8 heap nodes and the second one is the group for
native objects. At the moment we have two different sets of native
objects. There are 'Detached DOM trees' and 'Document DOM trees' type of objects.

I think it'd be nice to replace one group containing all native objects with
separate groups for different types of native objects.

aae7033ba1 Fix JavaScript accessors on objects with interceptors. 
This fixes how Object.defineProperty() defines JavaScript accessors on
objects with installed API interceptors. The definition itself does not
cause any interceptors to be called, whereas any subsequent accesses on
said object will still fire the interceptor. This behavior is in sync
with API accessors.

it should update the internal value instead of redefinind the property

502039a6bd Fix invalid usage of StoreIC_ArrayLength optimization. 
This introduces an additional check into the StoreIC_ArrayLength builtin
checking that the array still has fast properties. Redifinitions of the
length property that would cause it's type or attributes to change, will
switch to slow properties, thereby invalidating said optimization.

This test deleted its working directory and then tried to run several

Changes:
-TEST_DIR is only removed at the very end of the test
-the working directory is changed to /tmp at the beginning so that
 every iteration (when running with --stress-opt) has a valid working directory

410219c8f3 Sync parser and preparser on do-while and return statements. 
This CL fixes the preparser to have the same liberal automatic semicolon
insertion behaviour as the parser. In the case of a return statement in
global code we throw a syntax error at runtime rather than an early error
due to compatibility with KJS. However that hack allowed the following
syntactically incorrect program in global code in the parser but not in
the preparser:
  if (false) return else {}
while the slightly saner version with the obligatory semicolon
  if (false) return; else {}
was disallowed in the parser, but the preparser allowed it. This CL also
fixes that issue.
