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.

# REQUIRES: aarch64-registered-target
[GlobalISel] Introduce G_BUILD_VECTOR, G_BUILD_VECTOR_TRUNC and G_CONCAT_VECTOR opcodes. These opcodes are intended to subsume some of the capability of G_MERGE_VALUES, as it was too powerful and thus complex to add deal with throughout the GISel pipeline. G_BUILD_VECTOR creates a vector value from a sequence of uniformly typed scalar values. G_BUILD_VECTOR_TRUNC is a special opcode for handling scalar operands which are larger than the destination vector element type, and therefore does an implicit truncate. G_CONCAT_VECTOR creates a vector by concatenating smaller, uniformly typed, vectors together. These will be used in a subsequent commit. This commit just adds the initial infrastructure.
