Don't imply -flto with -O4. We now saturate at -O3. llvm-svn: 189149

// -flto causes a switch to llvm-bc object files.
Recommit "Clang support for -flto=thin." This recommits r250398 with fixes to the tests for bot failures. Add "-target x86_64-unknown-linux" to the clang invocations that check for the gold plugin. llvm-svn: 250455

Driver: Handle -flto, -O4, and tweak -emit-llvm to match llvm-gcc. - -emit-llvm no longer changes what compilation steps are done. - -emit-llvm and -emit-llvm -S write output files with .o and .s suffixes, respectively. - <rdar://problem/6714125> clang-driver should support -O4 and -flto, like llvm-gcc llvm-svn: 67645
