  [MemCpyOpt] move SrcAlloca to the entry if transformation is performed (#67226)

This is fixup for
https://github.com/llvm/llvm-project/pull/66618#discussion_r1328523770 .
This transformation checks whether allocas are static, if the
transformation is performed. This patch moves the SrcAlloca to the entry
of the BB when the optimization performed.
