cbruni c0282f608c Add unittests to keep InstanceType lists in sync
STRUCT_LIST and INSTANCE_TYPE_LIST are now forced to have the same order
as the InstanceType enum.

Drive-by-fix 1: Move type check and cast functions closer together in objects-inl.h

Drive-by-fix 2: Remove unused instance types SIGNATURE_INFO_TYPE and  TYPE_SWITCH_INFO_TYPE.
