7ffc07dcf7 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.

1807c1a3c9 Add a call to AC_CONFIG_COMMANDS to ensure that llvm_src is set properly 
in the config.status script. This allows the AC_CONFIG_MAKEFILE macro to
work properly after it was changed to support sub-projects.

a8d9789a7a This macro cannot assume that the location of install-sh and mkinstalldirs 
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).
