arm: Fix bootstrap failure with rtl-checking
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.
gcc/ChangeLog:
2020-04-27 Andre Vieira <andre.simoesdiasvieira@arm.com>
* config/arm/arm.c (output_move_neon): Only get the first operand if
addr is PLUS.
