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.

Remove irrelevant references to legacy git repositories from compiler identification lines in test-cases. (Doing so only because it's then easier to search for references which are actually important and need fixing.) llvm-svn: 351200
