Change the way that test directory names are mangled to be much more
conservative. Mangle ny character which isn't a letter, number, or
underscore/dash.
This was empirically observed to be needed for Verilator v5.038 by
@ngraybeal.
Release Notes
scalatest.TestingDirectorydirectory name mangling to be very conservative. Now, mangle anything not a letter, number, underscore, or dash. This is overly conservative, but avoids a whack-a-mole problem with Verilator. This has been empirically needed for Verilator v5.038.
