arm: Fix support_vector_misalignment.

Robin Dapp · Robin Dapp · commit 53085a46e7f1 · 2025-10-10T11:01:42.000+02:00
In gcc-16-4314-g5e9eecc6686 I meant to remove all uses of TYPE
in support_vector_misalignment but apparently forgot this one.
Fixing by using the inner mode's size.

gcc/ChangeLog:

	* config/arm/arm.cc (arm_builtin_support_vector_misalignment):
	Remove use of type.
