Rob Timpe 5ac112b569 [dynamo] Graph break on on user-defined class in compiled region (#161670) ...

Currently, user-defined classes inside of a compiled frame will cause the whole
frame to be skipped by dynamo.  This change defers the Unsupported exception
until the __build_class__ builtin is actually called, which allows a graph break
to be inserted.
