Merge lib/Transforms into lib/ExecutionEngine.

Rename BCCTransforms to RSTransforms and ForEachExpand.cpp to
RSForEachExpand.cpp. These are RenderScript-specific stuffs.

Type of parameter passed to RSForEachExpand pass was also modified to
use "vector of pairs (function name, foreach signature)."

bcc_assert.h is removed in this commit.

This commit is not expected to change any sematics.
