MIPS: Reland r20974: Unify and simplify the FastCloneShallowArrayStub.

Original commit message:
- Don't bake in length/capacity into full codegen calls of stubs,
allowing boilerplates to increase their capacity without regenerating
code.
- Unify all variants of the clone stub into a single,
length-independent version.
- Various tweaks to make sure that the clone stub doesn't spill and
therefore need an eager stack frame.
- Handle all lengths of array literals in the fast case.

Prevent calls to ReturnValue::Set with pointer-valued types.
[2nd try, after the previous version broke the build]
Currently, this code will compile:
SomePointer* p = ...;
ReturnValue r = ...;
r.Set(p);
What happens is that ReturnValue::Set has no pointer-ish overloads, but
a bool one, and hence C++ will convert the pointer to a bool and use
the Set(bool) overload. In other words, the example above is equivalent
to: r.Set(p ? true : false); Which probably isn't what the author had
in mind. This change adds a Set(void*) overload whose body forces a
compile error, to prevent this from happening inadvertently. The only
use of this indeed turned out to be an error.
(Said error was fixed/removed in crrev.com/
267393002.)
Why was crrev.com/
240013004 reverted?
The orginal version compiled fine on gcc (+ MSVC), but not on clang.
There's no clang try-bots, but the ASAN-based buildbots used clang
and hence the build broke. I'm slightly unsure on why, but clang -
unlike those other compilers - eagerly compiled the non-compilable
setter, which predictably broke. Now, the non-compilable setter uses
the same template logic that all other, comparable cases use. I've
tried 'make qc' with both gcc and clang versions.

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().

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.

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.

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:

Remove symbol preparse data altogether.
Removing it seems to be a clear win on mobile: producing symbol data makes cold
parsing 20-30% slower, and having symbol data doesn't make warm parsing any
faster.
Notes:
- V8 used to produce symbol data, but because of a bug, it was never used until
recently. (See fix https://codereview.chromium.org/
172753002 which takes the
symbol data into use again.)
- On desktop, warm parsing is faster if we have symbol data, and producing it
during cold parsing doesn't make parsing substantially slower. However, this
doesn't seem to be the case on mobile.
- The preparse data (cached data) will now contain only the positions of the
lazy functions.
