This completes the initial pass over all of the C DRs.

This patch fixes a "failed to annotate CFG" error in
SIAnnotateControlFlow. The problem occurs when there are
divergent and uniform unreachable/return blocks in the same
region. In this case, AMDGPUUnifyDivergentExitNodes does not
create a unified block so the region contains multiple exits.

StructurizeCFG does not work properly when there are multiple
exits, so the neccessary CFG transformations do not occur along
divergent control flow. Subsequently, SIAnnotateControlFlow
processes the path to the divergent exit block, but may only
partially process blocks along a unform control flow path to
another exit block.

This patch fixes the bug by creating a single exit block when
there is a divergent exit block in the function.

This patch implements the serialization for annot_pragma_loop_hint.

This also enables use of OpenMP pragmas and #pragma unused which do not

[Clang] Fix Sema::ClassifyName so that it classifies EnumConstantDecl as NonType when they are brought into scope via using enum

Currently Sema::ClassifyName(...) in some cases when an enumerator is brought
into scope via using enum during lookup it can end up being classified as an
OverloadSet. It looks like this was never accounted for when using enum support
was implemented and we need to add a check to allow an EnumConstantDecl to be
classified as NonType even when it is a class member.

I had reverted this before the holiday week because a problem was reported with a related change (D137140 - scalable vector known bits in DAG).  I had initially confused the two patches, and then decided to leave this reverted out an abundance of caution.  Now that we're through the holiday week, reapplying.

I also roled in fixes for several post commit review comments that hadn't landed with the original change.

Original commit message

This is a continuation of the series of patches adding lane wise support for scalable vectors in various knownbit-esq routines.

The basic idea here is that we track a single lane for scalable vectors which corresponds to an unknown number of lanes at runtime. This is enough for us to perform lane wise reasoning on many arithmetic operations.
