Update makellvm to work with the brave new world of separate obj-root trees.
With these changes, you can still run makellvm directly from your source tree
as follows:
  % makellvm [toolname] ## looks for obj-root in default places (see below)
or
  % makellvm -obj obj-root [toolname] ## specify obj-root explicitly.

With the first from, `makellvm' checks the following places in order
and uses the first one that contains the file `Makefile.config':
(1) Your src-root directory
(2) /localhome/$USER/llvm

Regenerated for Chris's updates, which adds several runtime library
directories.

another trivial cleanup

Simplification of trip counting machinery.
  - make sure to check the indvar type before anything else (efficiency)
  - Make sure to insert the 'add' into the program, even though it'll be
    dead
  - Wrap code at 80 columns
  - Other minor cleanups to reduce indentation level

Don't explicitly use $SourceDir to find the tblgen files.  This causes make
some confusion when trying to generate files (it probably couldn't tell that
./file and $(SourceDir)/file may be the same file).
Now, just let VPATH find everything, and list the primary tblgen file first in
the list of dependencies so that we can just use $< to reference it in the make
rule.

This should hopefully fix the nightly tester.
