We expect that the majority of malloc'd memory held by V8 is allocated
in Zone objects. Introduce an Allocator class that is used by Zones to
manage memory, and allows for querying the current usage.

The CharacterRange constructor checks the input for validity. However,
CharacterRange::Singleton also uses the constructor and may have
kEndMarker as input, causing the check to fail.

The solution is to move the check to CharacterRange::Range and
consistently use it across the code base.

Adds support for cpu profiler logging to the interpreter. Modifies the
the API to be passed AbstractCode objects instead of Code objects, and
adds extra functions to AbstractCode which is required by log.cc and
cpu-profiler.cc.

The main change in sampler.cc is to determine if a stack frame is an
interpreter stack frame, and if so, use the bytecode address as the pc
for that frame. This allows sampling of bytecode functions. This
requires adding support to SafeStackIterator to determine if a frame is
interpreted, which we do by checking the PC against pre-stored addresses
for the start and end of interpreter entry builtins.

Also removes CodeDeleteEvents which are dead code and haven't
been reported for some time.

Still to do is tracking source positions which will be done in a
followup CL.

When doing advance at the start of an unanchored unicode regexp,
we do not have to care about surrogate pairs. If we actually advance
into the middle of a surrogate pair, the only choice is to also
consume trail surrogate as nothing else can match from there.

This reduces the emitted code slightly. By not having choice in the
loop, we do not have to push backtrack onto the stack, preventing
stack overflow.

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).
