Add CodeView enum cv_leaf_type

Make everything more gdb-friendly by using an enum for type constants
rather than #defines.

gcc/
	* dwarf2codeview.cc (enum cv_leaf_type): Define.
	(struct codeview_subtype): Use enum cv_leaf_type.
	(struct codeview_custom_type): Use enum cv_leaf_type.
	(write_lf_fieldlist): Add default to switch.
	(write_custom_types): Add default to switch.
	* dwarf2codeview.h (LF_MODIFIER, LF_POINTER): Undefine.
	(LF_PROCEDURE, LF_ARGLIST, LF_FIELDLIST, LF_BITFIELD): Likewise.
	(LF_INDEX, LF_ENUMERATE, LF_ARRAY, LF_CLASS): Likewise.
	(LF_STRUCTURE, LF_UNION, LF_ENUM, LF_MEMBER, LF_CHAR): Likewise.
	(LF_SHORT, LF_USHORT, LF_LONG, LF_ULONG, LF_QUADWORD): Likewise.
	(LF_UQUADWORD): Likewise.
