Expand runtimes test suite to include Go, Java, PHP, and Python.

This change adds functionality for running more languages using
the runtimes test suite. It divides the languages into separate
test functions, which each call the helper testLang function in the
runtimes_test.go file. This allows them to be run individually
or as a group.
