give instcombine some helper functions for matching MIN and MAX, and
...
implement some optimizations for MIN(MIN()) and MAX(MAX()) and
MIN(MAX()) etc. This substantially improves the code in PR5822 but
doesn't kick in much elsewhere. 2 max's were optimized in
pairlocalalign and one in smg2000.

The select instruction is not neccesarily in the same block as the
...
phi nodes. Make sure to phi translate from the right block.
This fixes a llvm-building-llvm failure on GVN-PRE.cpp

Enhance the previous fix for PR4895 to allow more values than just
...
simple constants for the true/false value of the select. We now
do phi translation etc. This really fixes PR4895 :)

implement PR4895, by making FoldOpIntoPhi handle select conditions
...
that are phi nodes. Also tighten up FoldOpIntoPhi to treat constantexpr
operands to phis just like other variables, avoiding moving constantexpr
computations around.

Change these tests to feed the assembly files to opt directly, instead

of using llvm-as, now that opt supports this.

Make use of the END. facility on all files > 1K so that we aren't wasting CPU
cycles searching for RUN: lines that we'll never find.
