Do not build intrinsic graph for signature polymorphic methods.
The InstructionBuilder cannot build HInvokePolymorphic for
an intrinsic graph. It would be rather useless to allow this
as signature polymorphic method intrinsics always need the
slow-path for unhandled cases, and we would therefore reject
the compiled code anyway. Instead, prevent the construction
of the intrinsic graph for signature polymorphic methods.
Test: testrunner.py --host --optimizing -t 712-varhandle-invocations
