By using .loc the assembler is a lot easier to read. The llvm-gcc
output already had no comments in it.

There are two possibilities, the output with .loc is incorrect, in
which case reading the assembly and finding out that a ".loc 1 2 3"
should actually be ".loc 2 2 3" is not that hard.

The assembler (MC) is wrong. In this case you should be able to
compare the output of llvm-mc and the system assembler.
