[RFA/ARM] Fix latent bugs in parse_neon_mov

[Matthew Gretton-Dann]

This patch fixes some latent bugs in parse_neon_mov in gas/config/tc-arm.c.

On exit from parse_neon_mov *which_operand should reflect the index of 
the last operand parsed, and not the next operand to parse.  This was 
not done in all cases, and the attached patch fixes this.

This issue was identified whilst preparing a patch (forthcoming) to stop 
gas mis-accepting: vcvt.f64.s32 d0, s0, #11.

Tested on arm-none-eabi.

OK?

2011-12-06  Matthew Gretton-Dann  <matthew.gretton-dann@arm.com>

	* config/tc-arm.c (parse_neon_mov): Update which_operand
	correctly.
