for reasons explained in the comments, I also deactivated this code as it needs
more thought.

cf3cda8125 1 + 100 + 51 == 152, not 52. 
If we fold three constants together (c1+c2+c3), make sure to keep
LHSC updated, instead of reusing (in this case), the 1 instead of the
partial sum.

9340ba4bf9 Handle null a bit more carefully. 
Actually teach dsa about select instructions.  This doesn't affect the
graph in any way other than not setting a spurious U marker on pointer
nodes that are selected.

cedc75159d The install program doesn't know how to strip bytecode files so install 
bytecode as data, not program.

16f321bbe7 This instruction: 
X = gep null, ...

Used to not create a scalar map entry for X, which caused clients to barf.
This is bad.

d95ad13f8d Update to reflect various changes in the autoconf directory. THe 
recommended configuration of projects is now much simplified and depends
on LLVM file presence rather than local project file presence.

b56d560191 Remove auxilliary files that are now picked up from llvm/autoconf. This 
avoids version conflict problems with ltmain.sh (libtool), mkinstalldirs
and install-sh. This prevents projects from becoming stale when the LLVM
build system is upgraded or modified.

58a5e523ed * Move all the "standard" configuration stuff to the start of the file 
* Make the auxilliary directory be llvm/autoconf not the project's
* Use the LLVM_CONFIG_PROJECT macro to get the --with-llvm{src,obj} args
