The specification explicitly permits VMOV without size/data type suffix for
the case of moving between scalar and core register. The easiest way to deal
with that appeared to be to fake the suffix if none was specified.

	* gas/config/tc-arm.c (do_neon_mov): Fake an instruction suffix
	if there was none specified for moves between scalar and core
	register.

2013-04-09  Jan Beulich <jbeulich@suse.com>

	* gas/arm/neon-omit.s: Add tests for suffix less VMOV.
	* gas/arm/neon-omit.d: Update accordingly.
