Unifies the meaning of kRegCount8 and kRegCount16 across bytecodes.
Call and CallJSRuntime had a slightly different use of the register
count operand. From this change forth, register count operands are
always based off of the previous register operand.

This clears the currently pending message object whenever a try-block or

to avoid memory leaks introduced by the message object. Also the message
object is being restored when a finally-block exits.

This was inconsistent in the spec in case of has vs get, set. Removing
receiver==holder simplifies the lookup; so tentatively removing this
additional check which was broken until yesterday anyway. See

This includes 2 fixes:
1) We didn't properly advance the holder when checking whether
Receiver==Holder, so we'd inadvertently block loading the property if
the first property we find is on the typed array.
2) Reflect.get may cause any object on the prototype chain of the holder
to be the receiver; so we need to recheck for this special state for
each object we perform lookup on.

Moves the temporary register allocator out of the bytecode array
builder into TemporaryRegisterAllocator class and adds unittests.
Particular must be taken around the translation window boundary
motivating the addition of tests.

Also adds a Clear() method to IdentityMap() which is called by
the destructor. This allows classes to hold an IdentityMap if
they are zone allocated. Classes must call Clear() before the zone
is re-cycled or face v8 heap corruption.

We don't have proper test coverage for the no-deoptimization code paths
in the JSGlobalObjectSpecialization reducer, and we will properly never
have any use for that code, so it just adds complexity and code that

Revert of [regexp] implement /ui to mirror the implementation for /i. (patchset #2 id:20001 of https://codereview.chromium.org/1641613002/ )

Reason for revert:
This test fails:

assertEquals(["as"], /^a[\u017F]/ui.exec("as"));

The reason is that we end up with a character class that is not stand alone, so we do not perform case folding on it correctly (with unicode flag).
