My compilers class requires us to find a yacc grammar for one of these languages and combine it with the tokenizer we wrote. Presumably this is something easy to Google but I can't find it and my classmates are struggling as well. A yacc grammar for any of those three languages would suffice.

This might work for you: http://www.antlr.org/grammar/1153976512034/ecmascriptA3.g

The grammar at the bellow link uses LALR parser(see [Changelog][1]) same as Yacc, I think is much closer to what you need than ANTLR wich usees LL according to this answer: Can a ANTLR grammar file be modified to be used by PLY?
You can find the LALR Ecmascript grammar here: http://scriptonite.cvs.sourceforge.net/viewvc/scriptonite/scriptonite/src/ecmascript.grammar?revision=1.7
