[PATCH] D45255: [CodeGen] Add an option to suppress output of llvm.ident

There is a flag `-fno-ident` that has the same effect in GCC https://gcc.gnu.org/onlinedocs/gcc/Code-Gen-Options.html#index-fno-ident although it involves also ignoring the `#ident`.

A quick look seems to suggest that #ident is just ignored in the usual PP callbacks used by the parser so in practice `-fno-ident` would be the same as `-Qn`
