arm: Fix bootstrap failure with rtl-checking

Browse Source 
The code change that caused this regression was not meant to affect neon
code-gen, however I missed the REG fall through.  This patch makes sure we only
get the left-hand of the PLUS if it is indeed a PLUS expr.

	* config/arm/arm.c (output_move_neon): Only get the first operand if
	addr is PLUS.
