Neon: Fix Huffman enc. error w/Visual Studio+Clang The GNU builtin function __builtin_clzl() accepts an unsigned long argument, which is 8 bytes wide on LP64 systems (most Un*x systems, including Mac) but 4 bytes wide on LLP64 systems (Windows.) This caused the Neon intrinsics implementation of Huffman encoding to produce mathematically incorrect results when compiled using Visual Studio with Clang. This commit changes all invocations of __builtin_clzl() in the Neon SIMD extensions to __builtin_clzll(), which accepts an unsigned long long argument that is guaranteed to be 8 bytes wide on all systems. Fixes #480 Closes #490
