Logan Smith 715c72b4fb [NFC][analyzer] Return underlying strings directly instead of OS.str() ...

This avoids an unnecessary copy required by 'return OS.str()', allowing
instead for NRVO or implicit move. The .str() call (which flushes the
stream) is no longer required since 65b13610a5,
which made raw_string_ostream unbuffered by default.
