re PR rtl-optimization/82628 (wrong code at -Os on x86_64-linux-gnu in the 32-bit mode)
PR target/82628
* config/i386/predicates.md (x86_64_dwzext_immediate_operand): New.
* config/i386/constraints.md (Wf): New constraint.
* config/i386/i386.md (UNSPEC_SBB): New unspec.
(cmp<dwi>_doubleword): Removed.
(sub<mode>3_carry_ccc, *sub<mode>3_carry_ccc_1): New patterns.
(sub<mode>3_carry_ccgz): Use unspec instead of compare.
* config/i386/i386.c (ix86_expand_branch) <case E_TImode>: Don't
expand with cmp<dwi>_doubleword. For LTU and GEU use
sub<mode>3_carry_ccc instead of sub<mode>3_carry_ccgz and use CCCmode.
