[InstCombine] Transform bcopy to memmove 

bcopy is still widely used mainly for network apps. Sadly, LLVM has no optimizations for bcopy, but there are some for memmove. 
Since bcopy == memmove, it is profitable to transform bcopy to memmove and use current optimizations for memmove for free here.
