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.

[NVPTX] Only lower sin/cos to approximate instructions if unsafe math is allowed. Previously we'd always lower @llvm.{sin,cos}.f32 to {sin.cos}.approx.f32 instruction even when unsafe FP math was not allowed. Clang-generated IR is not affected by this as it uses precise sin/cos from CUDA's libdevice when unsafe math is disabled. Differential Revision: https://reviews.llvm.org/D28619 llvm-svn: 291936
