On a hash miss we need to call default if it is redefined in order to return the default value to be used. Previously we checked this with rb_method_basic_definition_p, which avoids the method call but requires a method lookup.
This commit replaces the previous check with BASIC_OP_UNREDEFINED_P and a new BOP_DEFAULT. We still need to fall back to rb_method_basic_definition_p when called on a subclasss of hash.

Use a BOP for Hash#default
On a hash miss we need to call default if it is redefined in order to
return the default value to be used. Previously we checked this with
rb_method_basic_definition_p, which avoids the method call but requires
a method lookup.
This commit replaces the previous check with BASIC_OP_UNREDEFINED_P and
a new BOP_DEFAULT. We still need to fall back to
rb_method_basic_definition_p when called on a subclasss of hash.
