Output CodeView type information for rvalue references
Translates DW_TAG_rvalue_reference_type DIEs into LF_POINTER types.
gcc/
* dwarf2codeview.cc (get_type_num_reference_type): Handle rvalue refs.
(get_type_num_array_type): Add DW_TAG_rvalue_reference_type to switch.
(get_type_num): Handle DW_TAG_rvalue_reference_type DIEs.
* dwarf2codeview.h (CV_PTR_MODE_RVREF): Define.
