x86-64/gas: fix an asymmetry in suffix/register checking 

Without this, constructs like "orw %rax, (%rax)" aren't being rejected
(other than any other wrong suffix/register combination).

2013-11-04  Jan Beulich <jbeulich@suse.com>

	* config/tc-i386.c (check_long_reg): Correct comment indentation.
	(check_qword_reg): Correct comment and its indentation.
	(check_word_reg): Extend comment and correct its indentation. Also
	check for 64-bit register.

	* gas/i386/x86-64-suffix-bad.[sl]: New.
	* gas/i386/i386.exp: Run new test.
