between them.

- Teach spiller to modify DBG_VALUE instructions to reference spill slots.

behavior for unsupported targets.  Add a new hook instead.

gets placed inside a main function, and should not itself be a main
function. This is silently hidden in GCC-hosted builds because the
inner main looks like a nested function declaration, which GCC supports.
In builds with compilers which do not support nested functions (by default),
this was causing an error, which caused these autoconf checks to fail, 
leaving their options disabled.

This fixes test/Feature/load_module.ll on x86_64-unknown-linux-gnu
llvm-gcc selfhost builds, among other things.

This also includes a regenerated configure, as the diff is small and telling.

Also, generalize ScalarEvolutions's min and max recognition to handle
some new forms of min and max that this change makes more common.
