Sanjay Patel 9530f18864 [InstCombine] (X << Y) / X -> 1 << Y ... ...when the shift is known to not overflow with the matching signed-ness of the division. This closes an optimization gap caused by canonicalizing mul by power-of-2 to shl as shown in PR35709: https://bugs.llvm.org/show_bug.cgi?id=35709 Patch by Anton Bikineev!
