Fixed a bug in ternary expression type evaluation that resulted in a false positive error. It was not properly handling the case where the condition was statically determined to be false or true.

* Sped up "find reference" by performing a quick text search for the reference symbol and avoiding additional work for that file if there is no chance of finding a reference within it.
* Avoid parsing the file if its contents don't contain the reference symbol text.
