A CodeBlock's StructureStubInfos shouldn't be in a Vector that we search using code origins and machine code PCs

This accomplishes a number of simplifications. StructureStubInfo is now non-moving,
whereas previously it was in a Vector, so it moved. This allows you to use pointers to
StructureStubInfo. This also eliminates the use of return PC as a way of finding the
StructureStubInfo's. It removes some of the need for the compile-time property access
records; for example the DFG no longer has to save information about registers in a
property access record only to later save it to the stub info.
        
The main thing is accomplishes is that it makes it easier to add StructureStubInfo's
at any stage of compilation.
