tell debug info which base register to use to reference a frame index on a
per-index basis. This is useful, for example, in the presence of dynamic
stack realignment when local variables are indexed via the stack pointer and
stack-based arguments via the frame pointer.

DIEs are created from MDNode, which are already uniqued. And DwarfDebug already uses ValueMaps to find and use existing DIE for a given MDNode.

"Attach debug info with llvm instructions" mode was enabled a month ago. Now make it permanent and remove old way of inserting intrinsics to encode debug info for line number and scopes.

While calculating original type size for a derived type, handle type variants encoded as DIDerivedType appropriately.
This improves bitfield support.

Fix DW_AT_data_member_location for bit-fields. It points to the location of annonymous field that covers respective field.

Do not held on to DenseMap slot accross map insertion. The insertion may cause the map to grow rending the slot invalid.
Use this opportunity to use ValueMap instead of DenseMap.

If there is not any llvm instruction associated with each lexical scope encoded in debug info then create such scope on demand for variable info.
