Fangrui Song 5b22bcc2b7 [X86][ELF] Prefer to lower MC_GlobalAddress operands to .Lfoo$local 
For a MC_GlobalAddress reference to a dso_local external GlobalValue with a definition, emit .Lfoo$local to avoid a relocation.

-fno-pic and -fpie can infer dso_local but -fpic cannot.  In the future,
we can explore the possibility of inferring dso_local with -fpic. As the
description of D73228 says, LLVM's existing IPO optimization behaviors
(like -fno-semantic-interposition) and a previous assembly behavior give
us enough license to be aggressive here.
