`syntax-errors` currently contains both syntax error tests (which don't need expansion) and tests for incorrect instantiations of the `count` metavariable expression (which do need expansion). Split the expansion-dependent tests to a separate file and remove unneeded invocations from `syntax-errors`, to ensure we are catching these before expansion.
