Subject: [patch, ARM] Fix PR48325, support POST_INC/PRE_DEC for NEON struct modes

This PR doesn't exactly trigger currently on trunk; a REG_DEAD note that
occurs in trunk, but not in the 4.5-based compilers which this bug was
reported for, currently blocks auto-inc-dec from doing its job, and just
happens to avoid this ICE.

The problem is vldmia/db, which do exist, are currently not enabled for
NEON struct modes (OI, XI, etc.)  This only needs a small patch to
neon_struct_mem_operand() to work. Okay for trunk?

Thanks,
Chung-Lin

	* config/arm/arm.c (neon_struct_mem_operand):
	Support POST_INC/PRE_DEC memory operands.
