This was not happening when there was no need to typecheck the entry.

Additional changes:
- Add tests with null table entries for typed and untyped function
  tables.
- Allow AddIndirectFunctionTable in wasm-run-utils to specify table
  type.
- Add possibility to define tables in test-gc.cc.
- Merge trapTableOutOfBounds with trapInvalidFunc.
- Use trapTableOutOfBounds in call_indirect as appropriate.
- Fix emission of table types in wasm-module-builder.cc.
