a5b2af0eae Parse and print DIExpressions inline to ease IR and MIR testing
Summary:
Most DIExpressions are empty or very simple. When they are complex, they
tend to be unique, so checking them inline is reasonable.

This also avoids the need for CodeGen passes to append to the
llvm.dbg.mir named md node.

See also PR22780, for making DIExpression not be an MDNode.

5d0334a48c Remove the obsolete offset parameter from @llvm.dbg.value
There is no situation where this rarely-used argument cannot be
substituted with a DIExpression and removing it allows us to simplify
the DWARF backend. Note that this patch does not yet remove any of
the newly dead code.

0bf7b18461 [LoopRotate] Propagate dbg.value intrinsics
Recommitting patch which was previously reverted in r297159. These
changes should address the casting issues.

The original patch enables dbg.value intrinsics to be attached to
newly inserted PHI nodes.
