I had to move the call to reset() (which clears parsing errors) to allow multiple compile commands.  This revealed an existing problem with compiler/ciReplay/TestVMNoCompLevel.java.  This test removes the last token from the "compile" line, trying to simulate a pre-2013 replay file.  Removing the last token is wrong if there are inlining tokens.  I could fix the test, but I don't see the value.  I don't think a 2022 JVM needs to read pre-2013 replay files.  If necessary, an old replay file can be edited to allow it to be parsed by a recent JVM.  I proposed to deleted the test and related workarounds in the code.
