[PATCH] D117721: [AMDGPU] Make v8i16/v8f16 legal

[Stanislav Mekhanoshin via Phabricator via llvm-commits]

rampitec updated this revision to Diff 402286.
rampitec added a comment.

- Added extract_subvector custom lowering which was missing.
- Added extract_subvector patterns for sub0_sub1 and sub2_sub3.
- Switched extract_elt to use cast to v2i64 for splitting instead of extract_subvector to avoid dag lowering loop.
