[llvm] r231298 - Teach DIEInteger to emit FORM_strp and FORM_ref_addr attributes.

Log:
Teach DIEInteger to emit FORM_strp and FORM_ref_addr attributes.

To be used/tested by llvm-dsymutil. (llvm-dsymutil does a 'static' link,
no need for relocations for most things, so it'll just emit raw integers
for most attributes)
