eb6e77f8cc MC-COFF: Fix (PR8278) temporary symbol relocations.

8f413fa9c0 On ELF we need to know which symbols are used in relocations to decide if 
they should be in the symbol table or not. Instead of "guessing", just compute
the symbol table after the relocations are known.

a8c02c3bdd Correctly produce R_X86_64_32 or R_X86_64_32S. 
With this patch in

movq    $foo, foo(%rip)
foo:
.long   foo

We produce a R_X86_64_32S for the first relocation and R_X86_64_32 for the
second one.

7070387f08 Make it possible for the MCObjectWriter to decide if a given fixup is fully 
resolved or not. Different object files have different restrictions and
different native assemblers have different idiosyncrasies we want to emulate
for now.

Move the existing MachO logic to the new place and implement an ELF one that
gets fixups to globals right.
