Subject: [PATCH] cmd/evm: move parseTestMetadata regexp to package-level var
 for efficiency

`parseTestMetadata` recompiles the regexp on every call (and it is invoked for every result printed). This adds avoidable overhead for large test runs. Move the compiled regexp to a package-level var and reuse it.
