[AMDGPU] Recognize x & ((1 << y) - 1) pattern.
Summary:
As a followup for D48007.
Since we already handle `x << (bitwidth - y) >> (bitwidth - y)` pattern,
which does not have ub for both the edge cases (`y == 0`, `y == bitwidth`),
i think also handling a pattern that is ub for `y == bitwidth` should be fine.
