Tests that use TestMain might never call m.Run(), and simply return
from TestMain. In that case, the iOS test harness never sees the
PASS from the testing framework and assumes the test failed.
Allow an exit with exit code 0 to also mean test success, thereby
fixing the objdump test on iOS.

First steps towards defining type aliases in the spec.
This is a nomenclature clarification, not a language change.
The spec used all three terms 'embedded type', 'anonymous field',
and 'embedded field'. Users where using the terms inconsistently.
The notion of an 'anonymous' field was always misleading since they
always had a de-facto name. With type aliases that name becomes even
more important because we may have different names for the same type.
Use the term 'embedded field' consistently and remove competing
terminology.
