But why would anyone want something that was
microcoded to run Pascal? 
Once upon a time, PASCAL was popular, and many people thought it was the
wave of the future.  Then C steamrolled over it.
  Are there any other languages that have gotten
microcoded into a processor? 
Many.  There was APL microcode for several IBM mainframes.  And just about
every language that ran on a Xerox D-machine (Alto, Dorado, Dolphin, Dandelion,
etc.) had its own special microcode.
