a7c743d3ac Reuse the gap move resolver. 
Rather than allocating a fresh gap move resolver for every parallel
move, use a single one per Lithium code generator.  This avoids always
reallocating the temporary zone-allocated lists used by the gap move
resolver.

426f13e084 Fix GC issue in instanceof stub 
The the call of the builtin in InstanceofStub was not correctly protected with an internal frame leading to the return address being handled as a pointer during GC.

Marked the Instanceof stub as allowing stub calls (the RecordWriteStub was removed some days ago).

This issue was not caught by the assertion designed for this when debug mode is run with --debug-code (which out tests always does) as generating code for Abort set the allow stub calls flag to true. This has been fixed by restoring the allow stub calls flag correctly.

2b7596a516 Instanceof slow case bind is incorrect. 
Currently, the bind for the slow label is after the pushing of the
args registers which renders the args pushing dead code because there
is a Ret preceeding it. The comments also imply that the arg pushing
should be part of the InvokeBuiltins tail call.

c1fd8bcf60 Fix a bug in deoptimization environments. 
The function HEnvironment::SetExpressionStackAt did not update the

environment for count operations and global function calls.

Reorganize class HEnvironment to make it fit V8's style a bit better
and to try to add some sanity to which C++ functions are intended to
be inlined.

Remove the flag --trace-environment which merely duplicated data in
the hydrogen.cfg file except without enough context to be useful.

1. Separating out the instance-type check from the array-length operation.

2. I also changed the bounds-check on keyed loads to use the length property
for JS arrays (like we do for array stores).

The new pattern should use less registers and allow more checks to be eliminated.

ace6290452 Fix issue 974. 
When entering a finally block in unoptimized code, we unconditionally
save the accumulator register in the stack in case it holds a return
value or an exception.  In the case of a break, continue, or falling
off the end of the try or catch block, this value is unpredictable and
not necessarily safe for GC.

b93a0f5d9a Second attempt: Improve our type feedback by recogizining never-executed IC calls for binary operations. 
This is an improved version of my earlier change r5970. It avoids degrading the
non-optimized code.

Initially we emit a conditional branch that is either always- or never-taken
after a smi-check (depending on whether we test for smi for for non-smi)
Since test-eax always sets the carry-flag to 0 we use jump-if-carry and
jump-if-not-carry.

The first invocation of the stub patches a jc with a jz and
jnc with a jnz-instruction so that the code looks exactly as it was
without patching. The only difference is the test- or nop-instruction
after the IC-call.
