44af185023 Restore behavior of PrepareForBreakpoints which was broken by r21145. 
Rename Debug::MaybeRecompileFunctionForDebugging to
EnsureFunctionHasDebugBreakSlots and ensure that it does
nothing if the function is unoptimized code with debug
break slots, otherwise, if the shared code has no
debug break slots, it recompile that shared code and
sets the function code to that shared code.

Also removes two incorrect ASSERTs.

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().

53bf126817 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 if csp is every set to a non-aligned value.  This CL ensures that csp is always aligned to 16 byte values on these platforms and adds checks to ensure this in debug mode.

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 implementer.
 - Rename PrepareForPush and PrepareForPop to PushPreamble and PopPostamble and move PopPostable after the pop.

a051bc5762 Next bunch of fixes for check elimination. 
- Canonicalize HCheckMapValue with constant map to
  HCheckMaps, and get rid of the special treatment
  during check elimination.
- Track only stable object maps for HConstants and
  add CHECK()s to verify state during code generation.

9c52caa86e Tighten up Object.observe code to ASSERT that it never deals with globals 
After r21126, Object.observe no longer allows observing the global proxy
object. This patch replaces codepaths that used to handle that case with
asserts showing that no such observation happens.

3274485c50 Store JSGlobalProxy's identity hash directly on the proxy itself 
Previously, the hash was stored on the underlying global object, since
it was stored in the hidden property table. This patch moves to an
implementation modeled on JSProxy, adding a new 'hash' field to JSGlobalProxy.

This allows storing the global proxy in a Map, Set, WeakMap, or WeakSet and
accessing it even after the proxy has been attached to a new global, which
is Firefox's current behavior and was the consensus of a recent thread on public-script-coord:
