re PR middle-end/78468 (libgomp.c/reduction-10.c and many more FAIL)
PR middle-end/78468
* emit-rtl.c (init_emit): Remove ??? comment.
* explow.c (get_dynamic_stack_size): Take known alignment of stack
pointer + STACK_DYNAMIC_OFFSET into account in lieu of STACK_BOUNDARY.
* config/sparc/sparc.h (INIT_EXPANDERS): In 32-bit mode, lower the
alignment of 3 virtual registers to BITS_PER_WORD.
* config/sparc/sparc.c (sparc_compute_frame_size): Simplify.
