Use gdbarch obstack to allocate the TYPE_NAME string in arch_type
Since the type whose name is being set is now being allocated on the gdbarch obstack, we should allocate its TYPE_NAME on the obstack too. This reduces the number of individual valgrind warnings for the command "gdb gdb" from ~300 to ~150. Tested on x86_64-unknown-linux-gnu. gdb/ChangeLog: * gdb_obstack.h (obstack_strdup): Declare. * gdb_obstack.c (obstack_strdup): Define. * gdbarch.sh (gdbarch_obstack_strdup): Declare and define. * gdbarch.c: Regenerate. * gdbarch.h: Regenerate. * gdbtypes.c (arch_type): Use gdbarch_obstack_strdup.
