Remove backend_field_index from backend codegen
e2f775a 
This method is un-needed as we can achieve the same result
by just reading the field offset from the `Layout`.

vm: add BytecodeBuilder and FunctionBuilder to build process
e5c9b37 
This hooks up the builder in preparation for where the builder methods
will be implemented in future commits.

codegen: simplify generating FnAbi from types
bfc5994 
Also, keep a record of the original type that was used to generate the
`FnAbi`. This saves us having to reverse the type and lead to
generating an type ID that mismatches the original type.

codegen: Avoid working with Instances directly

Prefer using `ReprTyId`s instead of instances. We can always
determine the instance from the type, but not vice versa.
