re PR target/82260 ([x86] Unnecessary use of 8-bit registers with -Os. slightly slower and larger code)
PR target/82260
* config/i386/i386.md (*movqi_internal): Replace (=q,q) alternative
with (=Q,Q), (=R,R) and (=r,r) alternatives, only enable the
latter two for 64-bit, renumber alternatives, for -Os imov (=q,n)
alternative always use QI mode, for -Os imov (=R,R) alternative
always use SI mode, for imov (=Q,Q) or (=r,r) alternatives
ignore -Os.
* gcc.target/i386/pr82260-1.c: New test.
* gcc.target/i386/pr82260-2.c: New test.
