Yuanfang Chen dd53274771 Revert "Revert "Reland "[Support] make report_fatal_error abort instead of exit"""
This reverts commit 80a34ae31125aa46dcad47162ba45b152aed968d with fixes.

Previously, since bots turning on EXPENSIVE_CHECKS are essentially turning on
MachineVerifierPass by default on X86 and the fact that
inline-asm-avx-v-constraint-32bit.ll and inline-asm-avx512vl-v-constraint-32bit.ll
are not expected to generate functioning machine code, this would go
down to `report_fatal_error` in MachineVerifierPass. Here passing
`-verify-machineinstrs=0` to make the intent explicit.
