  Revert "[AMDGPU] Split entry basic block after alloca instructions."

This reverts commit 98f47131228cc73b5308e3cc6fd70375808594e3.

Without any (theoretical/practical) guarantee that all the allocas within
*entry* basic block are clustered together at the beginning of the block,
this patch is doomed to fail. Hence reverting it.
