+1. The x86-64 SIMD functions now use a standard stack frame, prologue, and

+the C Huffman encoder (which is not used by default on x86 and Arm CPUs) to
+generate incorrect results if the Neon SIMD extensions were explicitly disabled
+at build time (by setting the `WITH_SIMD` CMake variable to `0`) in an AArch64
