* Implement `unionTypes(a, b *types.Type) *types.Type`

Implements type merging  building off of makeSimplifiedUnion.
The difference between siplified unions and merged types  are
in how structs are handled. In the former, we produce the intersection
of input structs to ensure the simplified type is a supertype of the input
types. In the later, we produce the union of the input structs which leads
to a type that is a subtype of all inputs.

Response to review and discussion
- Rename to MakeFullUnion to MakeMergedType
- Revert to old file naming
- Rename makeSimplifiedType to makeSupertype
- MakeUnion delegates to makeSupertype. Should prabably be be renamed, but
  this touches a lot of files, so keeping same for now.

fixes: #3204

* Rename to makeSimplifiedType and makeSimplifiedType2
