Rafael Espindola c7f355b8e1 Handle expressions of the form _GLOBAL_OFFSET_TABLE_-symbol the same way gas
does. The _GLOBAL_OFFSET_TABLE_ is still magical in that we get a R_386_GOTPC,
but it doesn't change the immediate in the same way as when the expression
has no right hand side symbol.

Rafael Espindola 7e0a793183 Handle reloc_signed_4byte in here. Not doing so was a regression from my
previous commit. It is strange that we see it in 32 bits. We already
have a fixme about it.

Rafael Espindola 0a7f336475 Handle the case of the magical _GLOBAL_OFFSET_TABLE_ showing up in a
symbol difference. This matches gas behavior and fixes PR11513.

We still don't handle _GLOBAL_OFFSET_TABLE_ in data sections.

Nick Lewycky 3e01bd3b60 Apparently, sometimes llvm-nm doesn't put the undefined symbol at the top. Take
that into account and test for no U's showing up in the middle, which is what
we really wanted to test for.

Nick Lewycky 29e7b315ac Also create a shndx even if there are no symbols. This lets us test
.symtab_shndx reading and writing together, and finally we have a testcase for
r141440.

Rafael Espindola 0fc5e89c82 ADD64ri32 sign extends its argument, so we need to use a R_X86_64_32S.
Fixes PR9934.

We really need to start tblgening the relocation info :-(

Rafael Espindola e90c1cb221 sets bit 0 of the function address of thumb function in .symtab
("T is 1 if the target symbol S has type STT_FUNC and the
symbol addresses a Thumb instruction ;it is 0 otherwise."

Rafael Espindola 1557fd6d39 Write the section table and the section data in the same order that
gun as does. This makes it a lot easier to compare the output of both

Eli Friedman d92d17bf67 PR9352: Always emit a relocation for weak symbols. Not emitting relocations
for calls to weak symbols with a definition has the appearance of working
with LLVM-generated code because weak symbol definitions are put in their
own sections.

Chris Lattner 78178749e9 split this test into arch specific pieces, so the ARM
test isn't run when the arm backend isn't built.  This
