Limit maximum number of IVs on a shape on T_OBJECTS

Create SHAPE_MAX_NUM_IVS (currently 50) and limit all shapes of
T_OBJECTS to that number of IVs. When a shape with a T_OBJECT has more than 50 IVs, fall back to the
obj_too_complex shape which uses hash lookup for ivs.

Note that a previous version of this commit
78fcc9847a9db6d42c8c263154ec05903a370b6b was reverted in
88f2b94065be3fcd6769a3f132cfee8ecfb663b8 because it did not account for
non-T_OBJECTS
