Regression fix: HForceRepresentation shouldn't be an idef.
...
Instead, code sites that are interested in underlying constant integer values
should use HValue::IsInteger32Constant(). The issue is that the infer representation phase shouldn't "see through" HForceRepresentation nodes to an underlying, and less specific representation.

Improvements in positions handling in optimizing compiler.
...
- When building binary arithmetic op and comparison restore source position of the operation itself before building operation itself after it was changed by building operands. This ensures that position recorded for operation points to the operation token instead of pointing to the rightmost operand;
- Add support for recording operands' positions and use these positions when inserting HChange instructions;
- When generating hydrogen.cfg emit H-instruction position as BCI (previously 0 was emitted), additionally on every lithium instruction emit annotation pointing to corresponding hydrogen-instruction. This allows to easily reach from deopt_id to lithium instruction and from it to hydrogen instruction and source position.

MIPS: Inline zero argument array constructor.
...
Port r17741 (fe14ef8)
Original commit message:
patch from issue 54583003 (dependent code).
Zero arguments - very easy
1 argument - three special cases:
a) If length is a constant in valid array length range,
no need to check it at runtime.
b) respect DoNotInline feedback on the AllocationSite for
cases that the argument is not a smi or is an integer
with a length that should create a dictionary.
c) if kind feedback is non-holey, and length is non-constant,
we'd have to generate a lot of code to be correct.
Don't inline this case.
N arguments - one special case:
a) If a deopt ever occurs because an input argument isn't
compatible with the elements kind, then set the
DoNotInline flag.

This is the exact copy of r17365 which was reverted in r17488 due to memory corruption. The root cause for the memory corruption - missing check for bump pointer limit before storing filler map must be addressed in r17626 where allocation hooks were removed from the generated code and left only in the runtime.
...
This is initial implementation of allocation profiler.
Whenever new object allocation is reported to the HeapProfiler and allocation tracking is on we will capture current stack trace, add it to the collection of the allocation traces (a tree) and attribute the allocated size to the top JS function on the stack.
Format of serialized heap snapshot is extended to include information about recorded allocation stack traces.
This patch is r17301 plus a fix for the test crash in debug mode. The test crashed because we were traversing stack trace when just allocated object wasn't completely configured, in particular the map pointer was incorrect. Invalid Map pointer broke heap iteration required to find Code object for a given pc during stack traversal. The solution is to insert free space filler in the newly allocated block just before collecting stack trace.

Magic fix for Math.sin/cos.
...
It turns out that Sunspider 1.0's 3d-morph verifies that the floating
point error must start with 6.

MIPS: Simplify behavior of code stubs that accept a variable number of stack arguments in addition to their parameters.
...
Port r17680 (cc0b972)
Original commit message:
Before, we'd add a special
variable to the environment with the value of a register with the
number of arguments. Now, that register just appears as a parameter to
the code stub.

Make HForceRepresentation an idef.
...
An optimization in the array constructor wasn't firing because the code
would check for constant values, failing to find them through
intervening HForceRepresentation instructions. Repaired this site. A
follow-on CL will provide a better way of making decisions based on
constant HValues.
