[gcov] Default coverage version to '408*' and delete CC1 option -coverage-exit-block-before-body gcov 4.8 (r189778) moved the exit block from the last to the second. The .gcda format is compatible with 4.7 but * decoding libgcov 4.7 produced .gcda with gcov [4.7,8) can mistake the exit block, emit bogus `%s:'%s' has arcs from exit block\n` warnings, and print wrong `" returned %s` for branch statistics (-b). * decoding libgcov 4.8 produced .gcda with gcov 4.7 has similar issues. Also, rename "return block" to "exit block" because the latter is the appropriate term.

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.

[gcov] Default coverage version to '407*' and delete CC1 option -coverage-cfg-checksum Defaulting to -Xclang -coverage-version='407*' makes .gcno/.gcda compatible with gcov [4.7,8) In addition, delete clang::CodeGenOptionsBase::CoverageExtraChecksum and GCOVOptions::UseCfgChecksum. We can infer the information from the version. With this change, .gcda files produced by `clang --coverage a.o` linked executable can be read by gcov 4.7~7. We don't need other -Xclang -coverage* options. There may be a mismatching version warning, though. (Note, GCC r173147 "split checksum into cfg checksum and line checksum" made gcov 4.7 incompatible with previous versions.)
