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.

497487beec Consistently use a separate Lithium instruction for flooring division. 
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.

10abff3498 Remove internalized cons string types. 
Currently, internalizing a cons string could result in either an
in-place converted internalized cons string or a newly created
internalized sequential string, depending on allocation success.

The former could end up being embedded into an IC, which is not
supported.
