Rafael Espindola baa3bf8f76 Bring r254336 back: 
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.
