History
Nadav Rotem 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.
