Subject: Updated to find source files using VPATH.  This makes writing build
 rules much cleaner and easier. Labeled .td as a suffix for tblgen files in
 Makefile.rules. Modified build rules so that source files generated during
 the build are placed in the build directory and not the source directory (and
 not in a Debug directory).  This makes the system cleaner and allows us to
 have a read-only source tree.
