Minor update to tests.

- drop yaml2obj in favor of using llc + objcopy
- remove c files

Note one tests now fails, though. 
For some reason w/ FatLTO the linker rewrites
 `xor %eax, %eax` to `movb $0x0, %al`.

I haven't figured out why, since the input files were generated the same way w/ llc,
and I've never seen a linker do that. I also confirmed that the input sections were identical.
