436849be6a TBAA: remove !tbaa from testing cases if not used. 
This will make it easier to turn on struct-path aware TBAA since the metadata
format will change.

3e883734fa During the CodeGenPrepare we often lower intrinsics (such as objsize) 
and allow some optimizations to turn conditional branches into unconditional.
This commit adds a simple control-flow optimization which merges two consecutive
basic blocks which are connected by a single edge. This allows the codegen to
operate on larger basic blocks.
