    M flang/lib/Frontend/FrontendAction.cpp

  Log Message:
  -----------
  [clang] Include the error message in file reading error diagnostic

in order to provide as much information as possible to the user. The
diagnostic will now look like for example:

  error: error reading '/tmp/foo.c': Permission denied

(This addresses a FIXME from 2019, 9ef6c49baf45)
