Use different method to mark DEX PC in the interpreter's CFI.
gdb handles unknown register numbers very ungracefully, so
we have to find a different way to insert the information.

Remove mterp reliance on code item layout
Pass dex instruction pointer intead of code item pointer to the mterp
entry code. This removes a dependency on the code item layout since it
may change in the future for compact dex.

Fix overlapping cfi ranges in mterp
Some residual .type and .size directives in mterp cause the

ART: Improve JitProfile perf in arm/arm64 mterp
ART currently requires two profiling-related things from the
interpreters: hotness updates and OSR switch checks. The hotness
updates previously used the existing instrumentation framework - which
is flexible, but quite heavyweight. For most things, the
instrumentation framework overhead is acceptable, but because we do a
hotness update on every backwards branch the overhead is unacceptable.
Prior to this CL, branch profiling dominates interpreter cost.
Here, we bypass the instrumentation framework for hotness updates
and deliver a significant performance improvement. Running
interpreter-only (dalvikvm -Xint) on a Nexus 6, we see the logic
subtest of Caffeinemark improving from 2600 to 9200, and the
overall score going from 1979 to over 3000. Compared to the
C++ switch interpreter, we see a 6x improvement on the branchy logic
subtest and a 2.6x improvement overall.
Compared with the previous mterp which did not have support for
jit profiling, we see a few (1% to 5%) performance loss on the
standard command-line benchmarks. I consider this acceptable
(we could create an alternate non-profiling mterp which would
have no penalty, but I don't consider this overhead big enough to
justify that).

Looks like some of our assemblers disagree on valid arm64 assembly syntax
Force use of clang for art runtime. In a subsequent CL, will use form
that both gcc and clang accept.
