[HIVE-3281] Alter table ignores table/partition not existing in semantic analysis

Description

In the method addInputsOutputsAlterTable in the DDLSemanticAnalyzer we get the table and partition being altered from the metastore. Failures to get these are quietly ignored, even though they resurface during query execution. We can throw a semantic exception here instead of ignoring them and save some time/resources. Also, by doing it here we save on retrieving the table/partition from the metastore since we're doing it here already.
