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().

Patch by Paul Lind.

fa2ff742ed Adjust unit test to avoid flakyness when running with the ARM simulator. 
In some cases the assert that the test function is not optimized fails
because the function may be optimized already after the second invocation.
(e.g. when running slow in debug mode)

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

This eliminate redundant HChange instructions and allows range information of
converted values propagated across control-flow splits.

It fixes the performance regression on code like:

if (x > 1) {
  y = x - 1;
}

where we should eliminate the overflow check on the sub inside the if-statement.

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).

7939f9acf2 Make scanner handle invalid unicode escapes in identifiers correctly. 
I.e., don't just convert \u to u in identifiers (like in strings and regexps).

Also make the scanning of RegExp flags not interpret the escapes.

(Fix and reapply of r8942)
