Following bug#62508, I've taken a bit of a closer look at the compiler
regexp for ModelSim. I've modified it so that it can differentiate
between Errors, Warnings and Notes when highlighting. I also make use of
Xilinx Vivado at work, for which I've added a new compiler entry:

The patch was generated from the emacs master branch. I would greatly
appreciate it if these changes could find their way in some form into a
future emacs release.
