New arena memory allocator.
Before we were creating arenas for each method. The issue with doing this
is that we needed to memset each memory allocation. This can be improved
if you start out with arenas that contain all zeroed memory and recycle
them for each method. When you give memory back to the arena pool you do
a single memset to zero out all of the memory that you used.
Always inlined the fast path of the allocation code.
Removed the "zero" parameter since the new arena allocator always returns
zeroed memory.
Host dex2oat time on target oat apks (2 samples each).
Before:
real 1m11.958s
user 4m34.020s
sys 1m28.570s
After:
real 1m9.690s
user 4m17.670s
sys 1m23.960s
Target device dex2oat samples (Mako, Thinkfree.apk):
Without new arena allocator:
0m26.47s real 0m54.60s user 0m25.85s system
0m25.91s real 0m54.39s user 0m26.69s system
0m26.61s real 0m53.77s user 0m27.35s system
0m26.33s real 0m54.90s user 0m25.30s system
0m26.34s real 0m53.94s user 0m27.23s system
With new arena allocator:
0m25.02s real 0m54.46s user 0m19.94s system
0m25.17s real 0m55.06s user 0m20.72s system
0m24.85s real 0m55.14s user 0m19.30s system
0m24.59s real 0m54.02s user 0m20.07s system
0m25.06s real 0m55.00s user 0m20.42s system
Correctness of Thinkfree.apk.oat verified by diffing both of the oat files.

Entry point clean up.
Create set of entry points needed for image methods to avoid fix-up at load time:
- interpreter - bridge to interpreter, bridge to compiled code
- jni - dlsym lookup
- quick - resolution and bridge to interpreter
- portable - resolution and bridge to interpreter
Fix JNI work around to use JNI work around argument rewriting code that'd been
accidentally disabled.
Remove abstact method error stub, use interpreter bridge instead.
Consolidate trampoline (previously stub) generation in generic helper.
Simplify trampolines to jump directly into assembly code, keeps stack crawlable.
Dex: replace use of int with ThreadOffset for values that are thread offsets.
Tidy entry point routines between interpreter, jni, quick and portable.

Move assembler out of runtime into compiler/utils.
Other directory layout bits of clean up. There is still work to separate quick
and portable in some files (e.g. argument visitor, proxy..).

Create separate Android.mk for main build targets
The runtime, compiler, dex2oat, and oatdump now are in seperate trees
to prevent dependency creep. They can now be individually built
without rebuilding the rest of the art projects. dalvikvm and jdwpspy
were already this way. Builds in the art directory should behave as
before, building everything including tests.
