[PATCH] D108881: [clang][driver] Honor the last -flto= flag even if an earlier -flto is present

[Usman Nadeem via Phabricator via cfe-commits]

mnadeem added a comment.

Combined with the code in `else if (Triple.isAMDGPU())` since the code is identical.
Removed the code to add `-flto` in favour of `-flto=full` since both are equivalent: https://clang.llvm.org/docs/CommandGuide/clang.html#cmdoption-flto
