68ddff5f90 ARM: Change a number of lithium instruction operands to be in registers 
Using operands which could possible be in stack slots would require a load instruction anyway, so having the register allocator putting them into registers seems most logical.

c1fd8bcf60 Fix a bug in deoptimization environments. 
The function HEnvironment::SetExpressionStackAt did not update the
environment's history.  This function is used to patch the bailout
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.

BUG=1004

0a128e5ae7 Optimize array-length and fast element loads. 
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.

Two old id types are replaced by builtin function ids. We can use
these in the code generators to emit custom code for the selected
functions.

48d884de48 ARM: Fix heap number allocation in lithium-codegen-arm that assumed 
that ip can be used as a scratch register. This is not true because
ip is already used for something else in AllocateInNewSpace in the
macro assembler.

Explicitly allocate a temp register for use in the heap number
allocation instead.
