[PATCH] D153909: [AMDGPU] Always pass `-mcpu` to the `lld` linker

[Jon Chesterfield via Phabricator via cfe-commits]

JonChesterfield added a comment.

I thought lld did the right thing if you pass it raw IR, without specifying an arch, but on reflection it might just be silently miscompiling things. The test doesn't seem to involve a specific type of input file, does clang foo.ll -o a.out pass a mcpu flag along?

It's a bit weird that the architecture doesn't seem to be embedded in the IR file (e.g. you have to pass it to llc) but that's out of scope here
