Evict selftest tempfiles from the diagnostics file cache
Selftests can use class selftest::temp_source_file to write out files for testing input-handling, and the files are unlinked in the dtor. This leads to stale entries in input.c's cache of file content, which could lead to errors if a temporary filename gets reused during a run of the selftests. We don't normally expect files to be "deleted from under us", so special-case this by adding a special way for temp_source_file's dtor to purge any cache entries referring to it. gcc/ChangeLog: * input.c (diagnostics_file_cache_forcibly_evict_file): New function. * input.h (diagnostics_file_cache_forcibly_evict_file): New declaration. * selftest.c (selftest::temp_source_file::~temp_source_file): Evict m_filename from the diagnostic file cache.
