if `CODEQL_EXTRACTOR_SWIFT_RUN_UNDER` env variable is set, and either * `CODEQL_EXTRACTOR_SWIFT_RUN_UNDER_FILTER` is not set, or * it is set to a regexp matching any substring of the extractor call then the extractor process is substituted with the command (and possibly options) stated in `CODEQL_EXTRACTOR_SWIFT_RUN_UNDER`, followed by the system arguments of the extractor itself (which should include the extractor program itself at the start). Before calling `exec`, `CODEQL_EXTRACTOR_SWIFT_RUN_UNDER` is unset to avoid unpleasant loops. An example usage is to run the extractor under `gdbserver :1234` when the arguments match a given source file.
