i386: Handle sign-extract for QImode operations with high registers [PR78952]
Introduce extract_operator predicate to handle both, zero-extract and
sign-extract extract operations with expressions like:
(subreg:QI
(zero_extract:SWI248
(match_operand 1 "int248_register_operand" "0")
(const_int 8)
(const_int 8)) 0)
As shown in the testcase, this will enable generation of QImode
instructions with high registers when signed arguments are used.
