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. Differential Revision: https://reviews.llvm.org/D24317 llvm-svn: 281990
