Namely, output the rellocation flags explicitly when loading constants.
Added benifit: save a load when loading from the constant pool.

Add support to the X86 backend for emitting ELF files. To use this, we
...
currently use: llc t.bc --filetype=obj
This will produce a t.o file which is dumpable with readelf. Currently
the file produced is empty, but the scaffolding to do more is now in place.

For now, the elf writer is only capable of emitting an empty elf file, with
