This commit updates aarch64 SIMD comparison (cmtst) patterns to accommodate a recent RTL simplification. The simplification rule (not (neg (eq x y))) to (neg (ne x y)) caused existing aarch64 patterns to fail, breaking a test case.
The patterns in aarch64-simd.md have been adjusted to recognize these new canonical forms, resolving the testsuite failure.
