a5a21a0da4 Move OS::MemCopy and OS::MemMove out of platform to utils
Since both are jitted on some platforms and depend on codegen, they
don't belong to the platform abstraction. At the same time, I can't put
them to codegen.h, as this would introduce cyclic dependencies.

2ba3716e4a Reland - Arm64: Ensure that csp is always aligned to 16 byte values even if jssp is not.
Even although the Arm64 specification specifies that csp
only needs to be aligned to 16 bytes if it is dereferenced, some
implementations show poor performance.

Also makes the following change:
 - Enable CPU support for arm64 to enable probing of cpu implementer and cpu part.
 - Add ALWAYS_ALIGN_CSP CpuFeature for Arm64 and set it based on runtime probing of the cpu imp
 - Rename PrepareForPush and PrepareForPop to PushPreamble and PopPostamble and move PopPostabl

67ff68783a Arm64: Fix check errors on Arm64 debug after r21177.
r21177 added extra AssertStackConsistency() checks which
increased code size on debug and caused the assembler buffer
to be too large.  Increased some of these buffers to
compensate.

Also, ProfileEntryHoolStub could use the wrong number of
instructions for kProfileEntryHookCallSize depending upon
whether debug code was being emitted or ALWAYS_ALIGN_CSP was
enabled.  Fixed this by taking ALWAYS_ALIGN_CSP into account
and ensuring that no debug code is emitted during
MaybeCallEntryHook().

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.
