[PATCH] D39281: [libunwind] Express Registers_*::lastDwarfReg using _LIBUNWIND_HIGHEST_DWARF_REGISTER

I think one source of truth is better than two.  I do find the constant's value a bit off in general though.  That is, the name 'HIGHEST' implies to me that it is the highest value used, not N + 1 as we currently define it.
