ARMAsmParser and X86AsmParser doesn't process files without newline at the end
of file properly.

llvm-mc failed to parse file with error message:
nonl-x86.s:2:17: error: unexpected token in argument list

Reproduction steps:

1. Create the file "nonl-x86.s" with the next contents (or use attachment):
movl %gs:8, %eax
movl %gs:8, %eax

2. Ensure that it has no newlines at EOF.

3. run llvm-mc:
llvm-mc nonl-x86.s

4. llvm-mc fails with message:
nonl-x86.s:2:17: error: unexpected token in argument list
