PR rtl-optimization/26244
* cse.c (fold_rtx): Correctly associate shifts when const_arg1 and/or
inner_const are negative or greater than or equal to the bitsize of
MODE. If SHIFT_COUNT_TRUNCATED is false, the values aren't associated.
Otherwise, the values are masked using GET_MODE_BITSIZE (mode) - 1.
Simplify complicated if statement. For ASHIFT and LSHIFTRT, return
CONST0_RTX (mode) when the new shift count is greater than or equal to
to the bitsize of the object being shifted and XEXP (y, 0) has no side
effects.
