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.

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.

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

recommended configuration of projects is now much simplified and depends
on LLVM file presence rather than local project file presence.

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.

* 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

* Make aclocal look in LLVM's autoconf/m4 directory for macros
* Don't force generation of missing files

in the config.status script. This allows the AC_CONFIG_MAKEFILE macro to
work properly after it was changed to support sub-projects.

is in ${srcdir}/autoconf because that is only true if the project is LLVM.
For other projects (e.g. sample), we don't want to have to distribute the
mkinstalldirs or install-sh programs because it opens a window of breakage
for projects. So, this change requires that the llvm_src variable be set
up via another AC_CONFIG_COMMANDS call. For LLVM this is done in the
configure.ac. For projects its done in the LLVM_CONFIG_PROJECT macro.

takes care of the --with-llvmsrc and --with-llvmobj options for the project
It was moved here from the project's configure.ac file because there is
some tricky handling of the llvm_src variable to tell the project where the
llvm source tree is (for mkinstalldirs and install-sh commands).

This does a simple form of "jump threading", which eliminates CFG edges that
are provably dead. This triggers 90 times in the external tests, and
eliminating CFG edges is always always a good thing! :)

* Consolidate all "install" usage to the install program/script found by
autoconf which includes the autoconf/install-sh script if necessary
* Change Makefile.rules to not use the -D flag to install but use the
MKDIR command as necessary.
* Change Makefile.rules to differentiate between installation of executable
files and regular data files to get the permission modes correct.

The fact that llc bombed (in this case) is ok, but bugpoint shouldn't crash after this.
