[PATCH] D19033: ELF: Use hidden visibility for all DefinedSynthetic symbols.

[Peter Collingbourne via llvm-commits]

pcc created this revision.
pcc added reviewers: atanasyan, rafael, ruiu.
pcc added a subscriber: llvm-commits.

This simplifies the code by allowing us to remove the visibility argument
to functions that create synthetic symbols.

The only functional change is that the visibility of the MIPS "_gp" symbol
is now hidden. Because this symbol is defined in every executable or DSO, it
would be difficult to observe a visibility change here, so this seems safe,
but I'd like a MIPS expert to take a look.
