[PATCH] Fix PR66552, Missed optimization when shift amount is result of signed modulus

Hi, This patch wants to fix PR66552 on gimple and optimizes (x shift (n mod C)) to (x shift (n bit_and (C - 1))) when C is a constant and power of two as discussed in PR66552. The regression testing for the patch was done on GCC mainline on powerpc64le-unknown-linux-gnu (Power 9 LE) with
