c21cf2d334 Function calls are handled with a LoadIC and a FunctionCallStub. This works well, but we can create a platform to gather custom feedback by inventing a CallIC. CallIC takes a JSFunction as input, maintains UNINIT/MONO/MEGA state in a feedback slot, and engages in limited patching for the most efficient code. 
The change creates a degrade in NBody tests, but a follow-on CL addresses it by using this custom feedback platform to give a 45% improvement.

* The exclusive monitor does not need to be cleared by CLREX if a LDRX was
  not followed by a matching STREX.

* Use LDAR and STLR where possible.

bf1155e8a4 MIPS: Consistently use a separate Lithium instruction for flooring division. 
Port r20395 (5b802048)

Original commit message:
Previously we tried to share some code on by a slightly confusing re-use
of LDivI for a (general) flooring division. Now we cleanly separate
concerns, just like for the rest of the division-like operations. Note
that ARM64 already did it this way.

If we really want to save some code, we can introduce some macro
assembler instructions and/or helper functions in the code generator in
a future CL, but we should really try to avoid being "clever" to save
just a few lines of trivial code. Effort != complexity. :-)

Renamed some related Lithium operands on the way for more consistency.

d93c906acc Monomorphic prototype failures should be reserved for already-seen keys. 
We incorrectly mark a KeyedStoreIC miss as a monomorphic prototype
failure even though it's the first time a particular (string) key has
been seen.

cbeef7147f MSan workaround in Simulator::VisitBitfield. 
This change shuffles the code in Simulator::VisitBitfield a bit
to work around a MemorySanitizer bug. New code should not be any
slower or less readable than before.

725ce114aa MSan does not understand inline asm. This change preinitializes cpuid 
results, and disables the use of stos.

Random mmap() addresses conflict with sanitizer memory layout.

4fe93b2d22 [msan] Do not unpoison heap if running on simulator. 
With the simulator, MSan detects all memory accesses from JIT code
without the need for annotations.

We'd like to keep the annotation in the native (w/o simulator) mode
until we can move all MSan+V8 users to simulator mode.
