Subject: rtl-ssa: Fix reg_raw_mode thinko [PR98347]

rtl-ssa: Fix reg_raw_mode thinko [PR98347]

I'd used reg_raw_mode[regno] for general registers, even though
the array is only valid for hard registers.  This patch uses
regno_reg_rtx instead.

gcc/
	PR rtl-optimization/98347
	* rtl-ssa/access-utils.h (full_register): Use regno_reg_rtx
	instead of reg_raw_mode.
