ART: Implement a fixed size string dex cache
Previously, the string dex cache was dex_file->NumStringIds() size, and
@ruhler found that only ~1% of that cache was ever getting filled. Since
many of these string dex caches were previously 100,000+ indices in
length, we're wasting a few hundred KB per app by storing null pointers.
The intent of this project was to reduce the space the string dex cache
is using, while not regressing on time that much. This is the first of a
few CLs, which implements the new fixed size array and disables the
compiled code so it always goes slow path. In four other CLs, I
implemented a "medium path" that regresses from the previous "fast path"
only a bit in assembly in the entrypoints. @vmarko will introduce new
compiled code in the future so that we ultimately won't be regressing on
time at all. Overall, space savings have been confirmed as on the order
of 100 KB per application.
A 4-5% slow down in art-opt on Golem, and no noticeable slow down in the
interpreter. The opt slow down should be diminished once the new
compiled code is introduced.

Logging improvements for C++ / Java structure issues
When C++ and Java structures are different sizes or arranged
differently some log statements are useful but are hard to
pick out because they merge with other log lines. Adding
"\n" to the end of them makes it easier to read.

Always mark zygote large objects for CC
Prevent needing to gray holders of zygote large objects.
System wide zygote space PSS after boot:
12644 kB -> 5571 kB for CC.
Also PSS reduction in zygote large objects themselves since their
gray bit would have been set each GC.
Overall LOS savings hard to measure, could be up to 316 * 4KB per
app since there are 316 zygote large objects.
Also clear mod-union tables for image spaces to prevent dirty
image pages if any of the image spaces point to zygote large objects.
System wide .art mmap: 37432 kB -> 34372 kB
System server before (N6P):
LOS shared dirty: 12888 kB
Zygote space shared dirty: 700 kB
Zygote space private dirty: 868 kB

jni: Fast path for @FastNative annotated java methods
Adds a faster path for java methods annotated with
dalvik.annotation.optimization.FastNative .
Intended to replace usage of fast JNI (registering with "!(FOO)BAR" descriptors).
Performance Microbenchmark Results (Angler):
* Regular JNI cost in nanoseconds: 115
* Fast JNI cost in nanoseconds: 60
* @FastNative cost in nanoseconds: 36
Summary: Up to 67% faster (vs fast jni) JNI transition cost

Welcome to JavaFuzz as our latest A[a]rt tools team member!
Rationale:
JavaFuzz is tool for generating random Java programs with
the objective of fuzz testing the ART infrastructure. Each
randomly generated Java program can be run under various
modes of execution, such as using the interpreter, using
the optimizing compiler, using an external reference
implementation, or using various target architectures.
Any difference between the outputs (a divergence) may
indicate a bug in one of the execution modes.
