Skip warnings for some unresolved references.

Some applications rename the newer RTL attributes to the older
attributes in order to target RTL locales, but not need to include two
attributes everywhere it's needed. For example, iosched renames
paddingStart to paddingLeft (among other attributes) for API 17 and
above. This leads to hundreds of warnings about missing attributes.
This change suppresses such warnings.

Also, skip adding unresolved attributes to the typed array. This is more
in line with the actual implementation on device, and prevents
unexpected warnings/errors/crashes later.
