Add support for generating and saving the optimization record.
Optimization record lists the optimizations performed by LLVM.

This patch enables the flag in Flang. FlangOption added to all
variants of fsave-optimization-record in
clang/include/clang/Driver/Options.td . Clang handles it the
same way.

opt_record_file, opt_record_passes and opt_record_format flags
in Options.td were moved out of the group [CC1Option, NoDriverOption]
to allow flang -fc1 support.

The renderRemarksOptions and willEmitRemarks functions in
clang/lib/Driver/ToolChains/Flang.cpp follow same syntax as clang.
In flang/lib/Frontend/CompilerInvocation.cpp we update the field
OptRecordFile with the provided optimization file value. Clang
doesn't do this as it processes the Options.td, mapping the
OptRecordFile earlier on.
