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
a version HEAP_NUMBER that can handle -0.

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... ;-)
