*	Bring r254336 back:	Rafael Espindola	2015-12-01	1	-0/+13
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	The difference is that now we don't error on out-of-comdat access to internal global values. We copy them instead. This seems to match the expectation of COFF linkers (see pr25686). Original message: Start deciding earlier what to link. A traditional linker is roughly split in symbol resolution and "copying stuff". The two tasks are badly mixed in lib/Linker. This starts splitting them apart. With this patch there are no direct call to linkGlobalValueBody or linkGlobalValueProto. Everything is linked via WapValue. This also includes a few fixes: * A GV goes undefined if the comdat is dropped (comdat11.ll). * We error if an internal GV goes undefined (comdat13.ll). * We don't link an unused comdat. The first two match the behavior of an ELF linker. The second one is equivalent to running globaldce on the input. llvm-svn: 254418
