Emit S_COMPILE3 CodeView record

CodeView has an S_COMPILE3 record to identify the compiler and source language of the compiland.  This record comes first in the debug$S section for the compiland. The debuggers rely on this record to know the source language of the code.

There was a little test fallout from introducing a new record into the symbols subsection.
