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.

--- Comment #1 from Uroš Bizjak  ---
The patched compiler just happens to trigger the existing problem where:

(insn 188 416 379 18 (parallel [
(set (reg:SI 72 k4 [orig:121 _114 ] [121])
(ashift:SI (reg:SI 70 k2 [orig:112 ubound.0 ] [112])
(const_int 2 [0x2])))
(clobber (reg:CC 17 flags))
]) 811 {*ashlsi3_1}
 (nil))

gets split with a post-reload splitter a to non-existent:

(insn 429 416 379 18 (set (reg:SI 72 k4 [orig:121 _114 ] [121])
(mult:SI (reg:SI 70 k2 [orig:112 ubound.0 ] [112])
(const_int 4 [0x4]))) -1
 (nil))

Please note mask registers, which points to a post-reload splitter with too
broad predicates.
