frameworks/base: vectorize Bitmap operations

Enable gcc vectorizing optimizations for Bitmap operations within
libandroid_runtime.so.  Adds -ftree-vectorize -mvectorize-with-neon-quad
-fprefetch-loop-arrays to functions and compiles Bitmap.cpp in ARM mode
(necessary to enable vectorizing optimizations) for appropriate targets.

mInputMethodSession == null. For the messages

DO_UPDATE_SELECTION, DO_APP_PRIVATE_COMMAND

memory is leaked. This commit recycles the args freeing
the allocated memory.

ActivityManager: memoize for performance

isHighEndGfx and isLargeRam are frequently called upon.. isLargeRam very
frequently within the ActivityStack. these aren't going to change after
they're calculated the first time so subject them to a basic memoization.
FTW.

Enhance db dump performance

BufferedOutputStream can enhance db dump performance.
Especially, if the data for dump is bigger
and the dump is being processed in the main thread,
it could cause ANR for slow performance.
