i386: Tighten ashift to lea splitter operand predicates [PR109733]
The predicates of ashift to lea post-reload splitter were too broad
so the splitter tried to convert the mask shift instruction. Tighten
operand predicates to match only general registers.
gcc/ChangeLog:
PR target/109733
* config/i386/predicates.md (index_reg_operand): New predicate.
* config/i386/i386.md (ashift to lea spliter): Use
general_reg_operand and index_reg_operand predicates.
