  [OpenMP] Use `abort` not `error` for fatal runtime exceptions

See PR46515 for the rational but generally, we want to *really* abort
not gracefully shut down.

  Log Message:
  -----------
  [SROA][Mem2Reg] Do not crash on alloca + addrspacecast

SROA knows that it can look through addrspacecast but
PromoteMemoryToRegister did not handle them. This caused an assertion
error for the test case, exposed while running
`Transforms/PhaseOrdering/inlining-alignment-assumptions.ll` with D83978
applied.

  [Mem2Reg] Teach promote to register about droppable instructions

This is the first of two patches to address PR46753. We basically allow
mem2reg to promote allocas that are used in doppable instructions, for
now that means `llvm.assume`. The uses of the alloca (or a bitcast or
zero offset GEP from there) are replaced by `undef` in the droppable
instructions.

This is the second of two patches to address PR46753. We basically allow
SROA to promote allocas that are used in doppable instructions, for
now that means `llvm.assume`. The (transitive) uses are replaced by
`undef` in the droppable instructions.
