LOG: X86: add newline to end of FMA instruction comments.

The newline is used by Disassembler.cpp (`emitComments`) to work out how to
format them properly, and if there's no newline it goes into an infinite loop.

Unfortunately I couldn't get llvm-objdump to be affected, only the MacOS otool
utility which dlopens libLTO.
