[PATCH] SROA: Defer migrating the debug info for new allocas until after all partitions are created.

[Adrian Prantl]

Tiny update: Don't add the dbg.declare to DeadInsts. It's redundant because it will get removed automatically when the alloca is removed. It's also a bad idea to remove the same instruction more than once.
