[Frontend] Verify that the bitstream is not empty before reading
the serialised diagnostics

Clang should avoid calling report_fatal_error when the file with the serialised
diagnostics is empty. This commit changes Clang's serialised diagnostic reader,
now it reports an appropriate error instead of crashing.
