Change generator_drop's instance to that of generator for dump_mir

Browse source 
Otherwise the file name generated for generator_drop will become

core.ptr-drop_in_place.[generator@<FILEPATH>_<NUMBERS>].generator_drop.0.mir

instead of main-{closure#0}.generator_drop.0.mir which breaks a mir-opt
test.
