562fff35 - [SROA] Fix an error where SROA can leave "dead" allocas (#238897)

[SROA] Fix an error where SROA can leave "dead" allocas (#238897) SROA may fully replace allocas with their constituent parts, but in some cases it can leave behind "dead" allocas that have only droppable uses. The leftover allocas are can retain debug information conflicting with the debug information for the partitions they were split into, which may lead to assertions failures. This patch removes such "dead" allocas. Fixes https://github.com/llvm/llvm-project/issues/238154
