Lua VM tests

Unlike the rest of the test suites, the code in this folder doesn't test any (well, much) CC code. Instead, it ensures that the Lua VM behaves in a way that we expect.

The VM that CC uses (LuaJ and later Cobalt) does not really conform to any one version of Lua, instead supporting a myriad of features from Lua 5.1 to 5.3 (and not always accurately). These tests attempt to pin down what behaviour is required for a well behaved emulator.

These tests are split into several folders:

• / Tests for CC specific functionality, based on Cobalt/Lua quirks or needs of CC.
• puc: Tests derived from the PUC Lua test suite.
