  Log Message:
  -----------
  [flang][Driver] Preliminary support for -ftime-report (#122894)

The behavior is not entirely consistent with that of clang for the
moment since detailed timing information on the LLVM IR optimization and
code generation passes is not provided. The -ftime-report= option is
also not enabled since that is only relevant for information about the
LLVM IR passes. However, some code to handle that option has been
included, to make it easier to support the option when the issues
blocking it are resolved. A FortranSupport library has been created that
is intended to mirror the LLVM and MLIR support libraries.

Based on @tarunprabhu's PR
https://github.com/llvm/llvm-project/pull/107270 with minor changes
addressing latest review feedback. He's busy and we'd like to get this
support in ASAP.
