6f3efd80 - [X86] combineTruncatedArithmetic - move more of fold inside combinei64TruncSrlConstant

[X86] combineTruncatedArithmetic - move more of fold inside combinei64TruncSrlConstant Let combinei64TruncSrlConstant decide when the fold is invalid instead of splitting so many of the conditions with combineTruncatedArithmetic NOTE: We can probably relax the i32 truncation constraint to <= i32, perform the SRL as i32 and then truncate further. Noticed while triaging #141496
