4e049d4619 Include more information when printing phi nodes. 
Still a bit cryptic, but people interested in phi nodes should know what they're doing... ;-)

ffc6c7e56b Introduce local function declarations in Crankshaft and fix issue 1647. 
We have to emit code for declarations later into the body block
(and not into the start block) so that the environment contains
the correct values.

In order to capture the environment effect of the declarations
that generate code (function declarations) I inserted a separate
AST id and a HSimulate after the declarations are visited.

Also fixes handling deopt in named function expressions:

c6e42e1bfa Fix initial prototype of WeakMap function. 
The bootstrapper accidentally overwrote the constructor property of the Object
prototype because it used initial_object_prototype() as prototype for WeakMap.
Unfortunately this is not possible for experimental natives because they are
installed after the snapshot initialization finished.

4084e698c3 Fixed a bug in the chaining of fixup position 
The ARM and MIPS assemblers had a bug where they did not handle the last element
in the list of code positions correctly during the fixup of offsets for forward
jumps. This happened when the first instruction contained a forward jump to a
label, and that label was used in a forward jump later, too.

Unified the code for Assembler::next on ARM and MIPS while we were there.

Added test cases, even for ia32/x64, which seem to be correct, even I don't
fully understand why... %-}

9e2db4c0f0 MIPS: Fix KeyedStoreStubCompiler::GenerateStoreFastDoubleElement() 
Test regress-91013.js (to ensure that the stored value was returned) passed on mips
without this fix, since the input value (in value_reg, a0) also happens to be in
mips return value register v0 at the time of call.

But it is fragile to depend on that behavior, so an explicit move from a0 to v0
is warranted. This fix puts that move in the delay slot of the Ret().

a5001de29c Centralize code for freeing LargeObjectChunks, fixing an uncommit bug. 
Due to heavy copy-n-paste, the handling of guard pages was inconsistent and we
didn't uncommit exactly the region we previously committed. Furthermore, the LOG
calls weren't consistent, either.

a546e4a8dd Fixed bool <-> Executability confusion and improved typing a bit. 
Passing a value of type Executability to a function expecting a bool worked only
by accident (because of the order of values in the enum). But using boolean
parameters is often a bad idea, anyway, so we use Executability directly.

Just another example why implicit type conversions in C++ are a bad idea... :-P

99b4d756fc Insert representation changes before doing range analysis and fix a bug in Range::Copy. 
This improves our static type information by calculating the result type
of conversions (HChange) during range analysis. It allows e.g. to eliminate
the write barrier in the following example where it was not possible before:

function f(x) {
  var y = x + 1;
  if (y > 0 && y < 100) {
    a[0] = y;
  }
}


* Fix bug in Range::Copy. The minus-zero flags has to be preserved by default.

633e615b89 Improve memory usage of receiver type feedback. 
Some AST nodes (Property, Call, etc.) store either a list of receiver
types or a monomorphic receiver type. This patch merges the two fields
using a small pointer list. GetMonomorphicReceiverType() is now a
purely convenience function returning the first and only recorded
type.

This saves about 500K (of about 39M) on average when compiling V8
benchmark as measured by a simple patch adding a zone allocation
counter (https://gist.github.com/1149397).

808748b44d Do not use deprecated ARM instructions in DirectCEntryStub::GenerateCall. 
Non-ancient versions of the ARM-ARM explicitly deprecate most uses of the PC
within instructions and older ARM implementations have a non-predictable offset
(8 or 12) for some of these deprecated uses. Avoiding the deprecated instruction
costs us one additional instruction in DirectCEntryStub::GenerateCall, but this
should not cause any significant performance degradation.

The deoptimizer still uses the PC in a stm instruction, but it is a bit unclear
what to do about that, so simply a comment has been added to reconsider this in
the future.

06bea35f7f Simplify and optimize ToBoolean handling. 
Changing our builtin JavaScript code slightly, we can make sure that we never
see internal objects as arguments for ToBoolean at runtime. Removing that case
from the stub generator and crankshaft makes things a lot easier.

Heap numbers can never be undetectable (only strings and spec objects can), so
we can leave out a useless test.

Try to re-use a non-null register value when returning 'true' in some cases.

Removed special handling of the 'handle all' case, it will very probably never
happen in real code and only makes things more complicated.

Improved naming of the ToBoolean stubs a bit, reflecting the order in which
cases are handled in the code itself.

d941053dbe Revert "Revert "Fix a bug in scope analysis."" 
Reapply r8838 with a fix for the issue of function names.

Because function names can be added/changed/removed through the API,
remember whether the function is anonymous when initially parsed and use
that information when compiling.

b625ce2b6b Fix a bug in scope analysis. 
When recompiling code (e.g., when optimizing) we could incorrectly hoist
some function expressions.  This leads to incorrect results or a crash.  The
root cause was that functions were not correctly categorized as expression
or declaration at parse time.

This requires some extra hoops to prevent the print name "anonymous" for
functions created by 'new Function' from establishing a binding.
