Builds should be silent, else people learn to tolerate and ignore warnings.

Fixed.

Have a few CLs to fix errors/warnings I got when compiling with errorprone
locally so people don't get spammed with warnings when errorprone is enabled.
Also, removed making some errorprone errors to warn instead of fail (I had
initially thought this would be run on bots only, so made some errors not fail
so errors that occurred later in the build would be visible. However, it looks
like this is just going to become the default java compiler eventually for
everyone)
