liblzma: Fix building with NVHPC (NVIDIA HPC SDK).
NVHPC compiler has several issues that make it impossible to build liblzma: - the compiler cannot handle unions that contain pointers that are not the first members; - the compiler cannot handle the assembler code in range_decoder.h (LZMA_RANGE_DECODER_CONFIG has to be set to zero); - the compiler fails to produce valid code for delta_decode if the vectorization is enabled, which results in failed tests. This introduces NVHPC-specific workarounds that address the issues.
