Subject: [PATCH] aarch64: Minor initial adjustment tweak

This patch just changes a calculation of initial_adjust
to one that makes it slightly more obvious that the total
adjustment is frame.frame_size.

gcc/
	* config/aarch64/aarch64.cc (aarch64_layout_frame): Tweak
	calculation of initial_adjust for frames in which all saves
	are SVE saves.
