[AMDGPU] Use S_BITCMP0_* to replace AND in optimizeCompareInstr
These can be used for reversed conditions if result of the AND
is unused except in the compare:
s_cmp_eq_u32 (s_and_b32 $src, 1), 0 => s_bitcmp0_b32 $src, 0
s_cmp_eq_i32 (s_and_b32 $src, 1), 0 => s_bitcmp0_b32 $src, 0
s_cmp_eq_u64 (s_and_b64 $src, 1), 0 => s_bitcmp0_b64 $src, 0
s_cmp_lg_u32 (s_and_b32 $src, 1), 1 => s_bitcmp0_b32 $src, 0
s_cmp_lg_i32 (s_and_b32 $src, 1), 1 => s_bitcmp0_b32 $src, 0
s_cmp_lg_u64 (s_and_b64 $src, 1), 1 => s_bitcmp0_b64 $src, 0
