Resolve DanglingDbgValue of PHI nodes where the use follows dbg.value intrinisic.

This assertion is too restrictive, it does not apply for dangling dbg value nodes (nodes where dbg.value intrinsic preceds use of the value).

[AVX] Add TableGen classes for vector/subvector type constraints.
This will be used to check patterns referencing a forthcoming

[AVX] Add type checking support for vector/subvector type constraints.
This will be used to check patterns referencing a forthcoming
