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.
