+ * @summary Test various reverse bytes ideal transforms on X86(AVX2, AVX512) and AArch64(NEON).
+ *          For AArch64(SVE), we have a specific optimization,
+ *          ReverseBytesV (ReverseBytesV X MASK) MASK => X, which eliminates both ReverseBytesV
+ *          nodes. The test cases for AArch64(SVE) are in TestReverseByteTransformsSVE.java.
