This is a single request to backporting #131592, #132362, #132397, #132405, #132414, and #132426.
#131592 is saturation intrinsic naming change that aligned with GCC;
#132362 is a revert of prior merged new YMM rounding variants of existing instructions;
#132397, #132405, #132414, and #132426 remove the YMM rounding variants from new introduced AVX10.2 instruction. Together with #132362, they are to reflect the latest change of AVX10 white paper: https://cdrdv2.intel.com/v1/dl/getContent/784343
Although the changes look big, they are just straightforward removal or renaming, the risk is low. I think back porting to LLVM20 can reduce the scope of people who may use the unsupported instructions and future compatibility issues when switching LLVM20 to future version.
