Subject: [PATCH 129/157] [Backport][SME] vec: Add array_slice constructors
from non-const and gc vectors
Reference: https://gcc.gnu.org/git/?p=gcc.git;a=commit;h=15433c214df295f2281a90fcf283355b21beca0e
This patch adds constructors of array_slice that are required to
create them from non-const (heap or auto) vectors or from GC vectors.
gcc/ChangeLog:
2022-08-08 Martin Jambor <mjambor@suse.cz>
* vec.h (array_slice): Add constructors for non-const reference to
heap vector and pointers to heap vectors.
