Description
Should it check gencode first?
I'm having an issue with custom intellij-v4 plugin where I tried to use ANTLR 4.7.1. It is generating .interp files in source directory when I click in grammar file. This happens because Intellij plugin is creating antlr Tool and then calls process() with gencode = false to parse the grammar file. Tool is created with no arguments, so the output directory is empty. Probably assuming that no files will be created if gencode is false.

Research direction
Read tool/src/org/antlr/v4/Tool.java around line 400 and follow process() when gencode is false. Reproduce the no-argument Tool case described for the IntelliJ plugin, then confirm that parsing with code generation disabled leaves no .interp file in the source directory.
