[llvm] r219829 - Correctly handle references to section symbols.

[Rui Ueyama]

Previously, relocations applied to .rela.ctors sections in an object file
pointed to different .text.startup sections in the same file, but after
this patch they point to the same .text.startup section. Because this patch
handles section names, it's likely that there's something with that.

Sorry for the frequent and incomplete updates. I'll let you know once I get
a reproducible test case.
