[RFA/ARM] Add support for // comments

[Matthew Gretton-Dann]

Hi,

The following patch adds support for // comments in gas targeting ARM.

This has been done to help support ARM AArch64 Assembler syntax which uses
// comments.  See the ARMv8 Instruction Set Overview available at:

http://infocenter.arm.com/help/topic/com.arm.doc.genc010197a/index.html

OK?

Thanks,

Matt
