Reduce and speed-up class def searches.

Use the class linker for descriptor lookups from the compile driver so that
dex caches are populated.
Reduce the scope of functions for scanning class paths to just the class
linker where they are performed.
If we see more than a threshold number of find class def misses on a dex file
lazily compute an index, so that future lookups are constant time (part of the
collection code is taken from
https://android-review.googlesource.com/#/c/103865/3). Note that we take a lazy
approach so that we don't serialize on loading dex files, this avoids the
reason the index was removed in 8b2c0b9abc3f520495f4387ea040132ba85cae69.
Remove an implicit and unnecessary std::string creation for PrintableString.

Quick compiler: Fix MIPS build

b/16484538

In debug builds, the Quick compiler frequently runs a sanity checker
over the register pool.  Among other things, it attempts to verify
consistent representation of register pairs.  However, a register's
"wide" flag is meaningful only when the register pair is associated
with a Dalvik wide value (sreg != INVALID_SREG) rather than a temp
wide value.

The MIPS build was tripping over this bad assertion.  Fixed here.

Also added a runtime option for changing the non moving space size:
-XX:NonMovingSpaceCapacity.
