Peter Collingbourne a5aa0c46c3 Introduce -funique-source-file-names flag. ...

The purpose of this flag is to allow the compiler to assume that each
object file passed to the linker has been compiled using a unique
source file name. This is useful for reducing link times when doing
ThinLTO in combination with whole-program devirtualization or CFI,
as it allows modules without exported symbols to be built with ThinLTO.
