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
INSERT_SUBVECTOR SDNode and will also be used to check
EXTRACT_SUBVECTOR nodes.

[AVX] Add type checking support for vector/subvector type constraints.
This will be used to check patterns referencing a forthcoming
INSERT_SUBVECTOR SDNode.  INSERT_SUBVECTOR in turn is very useful for
matching to VINSERTF128 instructions and complements the already
existing EXTRACT_SUBVECTOR SDNode.

using a TargetData. This fixes PR8968, though the testcase
is awkward to reduce.

Also, update several off GetUnderlyingObject's users
which happen to have a TargetData handy to pass it in.
