[PATCH] D18667: ELF: Add flag for controlling LTO optimization level.

[Mehdi AMINI via llvm-commits]

Slightly off-topic: ld64 does not have this option, and we're not willing to add it. We have been discussing internally about how to communicate the "opt level" to the linker plugin, and we were thinking about some kind of metadata that would carry the configuration (including things like "fast-math" or other codegen related options).
I'm interested in your opinion :)
