    	dwarf.h: Remove non-existing DW_TAG_mutable_type.
    
    	The DW_TAG_mutable_type was only mentioned in an early draft of DWARFv3.
    	But was removed because there are no C++ mutable qualified types. It was
    	replaced by a new attribute DW_AT_mutable on DW_TAG_member DIEs. The new
    	attribute is available in dwarf.h.
    	http://dwarfstd.org/ShowIssue.php?issue=050223.1
    
    	DW_TAG_mutable_type was only used internally in some backends (which
    	just ignored it anyway).  dwarves did use it to turn it into a string
    	value, libabigail used it and ignored it (patches to remove sent).
    	GCC, GDB and binutils don't use nor define it.
