Pull request overview
This PR updates CoreCLR JIT hardware-intrinsic metadata so CreateGeometricSequence is treated as a special-import, no-codegen intrinsic (rather than an InvalidNodeId intrinsic). This allows the intrinsic to exist as a GenTreeHWIntrinsic node (when applicable) and be expanded/optimized by later phases instead of being categorically treated as “invalid node”.
Changes:
- Update xarch intrinsic list entries for
Vector128/256/512.CreateGeometricSequencetoHW_Flag_SpecialImport|HW_Flag_NoCodeGen(preserving AVX-only compatibility where relevant). - Update arm64 intrinsic list entries for
Vector64/128.CreateGeometricSequencetoHW_Flag_SpecialImport|HW_Flag_NoCodeGen.

This is a leftover from #127690.
We need to annotate
CreateGeometricSequenceas non-invalid node as it might be left as GenTree node to benefit from constant propagation.@tannergooding
