[Clang][Driver] Remove -M group options before generating crash diagnostics

[Clang][Driver] Remove -M group options before generating crash diagnostics

Previously, when using '-MF file.d' on the command line, 'file.d' would not be deleted after a compiler crash.

The code path in Compilation::initCompilationForDiagnostics()  that was modifying 'TranslatedArgs' had no effect, because 'TCArgs' was already created after the crash.

This was covered by clang/test/Driver/output-file-cleanup.c, the test was succeeding by fluke because Driver::generateCompilationDiagnostics() would fail to launch the subsequent clang -E (see D74070 for a fix for this). So the test was only covering Driver.cpp, C.CleanupFileMap().
After this patch, both cleanup and removal of -MF are exercised.
