NEON gas undefined symbol bug

[Paul Brook]

The ARM NEON instruction "vmov d0, d1" incorrectly causes the output file to 
contain an undefined symbol "d1".

parse_neon_mov checks for Dn, #imm before it checks for Dn, Dm.  The immediate 
parsing routine uses expression() via parse_big_immediate and my_get 
expression.  This routine also parses symbols, which remain even after 
parse_big_immediate rejects the expression.

The fix is to check for the register case first.

Applied to CVS head.

	* config/tc-arm.c (parse_neon_mov): Parse register before immediate
	to avoid spurious symbols.
