More allocation code optimizations.

- Inline Class::AllocObject() and Array::Alloc().
- Inline some short Mutex functions and add LIKELY/UNLIKELY to some
  Mutex functions.
- This change improves the Ritz MemAllocTest by ~6% on Nexus 4 and
  ~10% on host.

Remove memory leaks

Change-Id: I13a74791b1d39edfbba7c7884057fa163c343a9a
Reduce memory allocation in verifier.

Remove the use of a map PcToRegisterLineTable for efficiency (matches Dalvik).
Place the register line register values inside the RegisterLine, saves a
secondary allocation and indirection.
Avoid the use of a deque in RegisterLine to avoid an allocation.
Simplify the SirtRef destructor in non-debug builds.
Saves >100ms from the two threaded compile time of ThinkFree on host.

Remove four counter increments out of the allocation path.

- This change removes the four allocation counters (the number of
bytes allocated, the number of objects allocated, the number of bytes
allocated ever, the number of objects allocated ever) from the
dlmalloc space allocation path. Now those counter values are computed
on the fly based on a combination of the two new counters that are
incremented by the GC side (the number of bytes freed ever and the
number of objects freed ever) and mspace_inspect_all() calls.

- This results in a 1-2% speedup (though with some noise) in Ritz
MemAllocTest on Nexus 4.

Fix intrinsification of floatToRawIntBits.

Accidentially lost in quick refactoring in
commit fa57c47f1b72916371a9c2d5c1389219bce655b4.

Fix incorrect initial dex cache size.

We were previously setting it to be sizeof(DexCacheClass) instead
of sizeof(DexCache). This was causing some problems with
compaction when I relied on the object sizes being accurate to
visit objects in the bump pointer space.

Avoid verifier crash for quickened invoke on null.

When verifying an invoke-virtual-quick on a "null" instance, we can't infer the
class of the method being invoked. This CL handles this case and avoid a crash
due to a failed check in RegType::GetClass.

Also revert changes made to test 082-inline-execute since it succeeds with this
CL now.

Also avoid building a string one character at a time.
