Merge inherits interface members#5359

Previously it assumed that if a class was present in the merge, only the class base types needed to be used. This became false when classes and interfaces could be merged.
Both interfaces and classes have base classes/interfaces; all members are available on an instance of the merged child.
A couple of tests were previously updated to give an incorrect error message.

I forgot to update the baselines in the last commit. I'll update them shortly to fix the build. |
I found that merging a class that has no base with an interface that has a base class causes a crash because `getDefaultConstructSignatures` assumes that any base must be a class base. Which was true in the previously buggy state.
Covers the case when the merged interface extends an interface, but the merged class does not extend a class, then trying to extend that class.

There was a problem hiding this comment.
i would move this to the bottom where it is used. this way we are not creating an empty array literal for every class. so that classes with no base types can share the sentinel empty array value.

We will need to cherrypick this into release-1.7 |

Fixes #5347
This bug has been around since July but we didn't notice it until recently.
getBaseTypesassumed that if a class was present in the merge, only the class base types needed to be used -- it skipped the interface base types entirely. This became false when [ambient] classes and interfaces could be merged.
