This is the build failure of the Ada runtime for Aarch64 targets.  The Aarch64 
back-end now asserts that the main variant of scalar types has TYPE_USER_ALIGN 
cleared, and that's not the case for scalar types declared with a confirming 
alignment clause in Ada.

Tested on Aarch64/Linux by Richard S. (thanks!) and on x86-64/Linux by me, and 
applied on the mainline.

	PR bootstrap/109510
	* gcc-interface/decl.cc (gnat_to_gnu_entity) <types>: Reset align
	to zero if its value is equal to TYPE_ALIGN and the type is scalar.
	Set TYPE_USER_ALIGN on the type only if align is positive.
