tools: libdeflate: update to 1.20

Changes: * Improved CRC-32 performance on recent x86 CPUs by adding VPCLMULQDQ-accelerated implementations using 256-bit and 512-bit vectors. * Improved Adler-32 performance on recent x86 CPUs by adding VNNI-accelerated implementations using 256-bit and 512-bit vectors. * Improved CRC-32 and Adler-32 performance on short inputs. * Optimized the portable implementation of Adler-32. * Added some basic optimizations for RISC-V. * Dropped support for gcc versions older than v4.9 (released in 2014) and clang versions older than v3.9 (released in 2016). * Dropped support for CRC-32 acceleration on 32-bit ARM using the ARMv8 pmull or crc32 instructions. This code only worked on CPUs that also have a 64-bit mode, and it was already disabled on many compiler versions due to compiler limitations. CRC-32 acceleration remains fully supported on 64-bit ARM. Signed-off-by: Robert Marko <[email protected]>
