This change fixes when a method body has only inline tags that produce no
output, the method summary will get eaten.
This change allows `{@inheritDoc}` from empty parents to go through the code
path used by `-nocomment` and properly generate tables.
All `jtreg:test/langtools/jdk/javadoc/doclet` tests pass.
