Sync libiberty and include with GCC for get_DW_UT_name.
This adds a get_DW_UT_name function to dwarfnames using dwarf2.def for use in binutils readelf to show the unit types in a DWARF5 header. include/ChangeLog: Sync with GCC * dwarf2.def: Add DWARF5 Unit type header encoding macros DW_UT_FIRST, DW_UT and DW_UT_END. * dwarf2.h (enum dwarf_unit_type): Removed and define using DW_UT_FIRST, DW_UT and DW_UT_END macros. (get_DW_UT_name): New function declaration. libiberty/ChangeLog: Sync with GCC * dwarfnames.c (get_DW_UT_name): Define using DW_UT_FIRST, DW_UT and DW_UT_END.
