Add reserve area to allocation stacks.
This fixes an issue with heap verification which was caused when
the allocation stack overflowed. This resulted in heap verification
failures since we were storing the newly allocated object in a
handle scope without having it be live either in the live bitmap
or allocation stack. We now push the object in the reserve area
before we do a GC due to allocation stack overflow.

Rewrite BitVector index iterator.
The BitVector::Iterator was not iterating over the bits but
rather over indexes of the set bits. Therefore, we rename it
to IndexIterator and provide a BitVector::Indexes() to get
a container-style interface with begin() and end() for range
based for loops.
Also, simplify InsertPhiNodes where the tmp_blocks isn't
needed since the phi_nodes and input_blocks cannot lose any
blocks in subsequent iterations, so we can do the Union()
directly in those bit vectors and we need to repeat the loop
only if we have new input_blocks, rather than on phi_nodes
change. And move the temporary bit vectors to scoped arena.

Fix InternTable::Lookup()/Remove() for hash code collisions.
When we have a hash code collision but the string is not yet
in the intern table, the old Lookup() would iterate until
the end of the table, i.e. it was up to linear in the size
of the table rather than linear in the number of colliding
hash codes.
And though the multimap::find() is implemented in terms of
lower_bound() in the standard library we're using, this
requirement doesn't seem to be in the C++ standard. It was
therefore wrong to assume that we will iterate across all
hits when starting from the iterator returned by find().

Method inlining across dex files in boot image.
Fix LoadCodeAddress() and LoadMethodAddress() to use the dex
file in addition to the method index to uniquely identify
the literal. With that fix in place, when we have both the
direct code and the direct method, we can safely pass the
actual target method id instead of the method id from the
same dex file in the method lowering info. This was already
done for calls from apps into boot image (and thus there was
a bug with a tiny risk of the wrong literal being used) and
now we also do that for calls within the boot image. The
latter allows the inlining pass to inline many more methods
than before in the boot image.

Add a read barrier for weak roots in monitors.
A weak root requires a read barrier for the to-space invariant to hold
because the object pointed to by a weak root can't be marked/forwarded
like the one pointed to by a strong root (GC does not know if it's
alive or not at that point) and because, without a read barrier, a
mutator could access it and obtain a from-space reference, which would
violate the to-space invariant.
TODO: do similar for the other types of weak roots.
