*FINALLY* Fix a really nasty nondeterministic bug that has been haunting us
since May 1st.  In this code, the pred iterator was being invalidated sometimes
causing the wrong entries to be added to PHI nodes.

The fix for this is to defererence and safe the *PI value before we hack on
branch instructions, which changes use/def chains, which SOMETIMES invalidates
the iterator.

Comment out the isnan stuff until we get a proper autoconf test for it
breaking the build on sparc is not acceptable.

Make order of argument addition deterministic.  In particular, the layout
of ConstantInt objects in memory used to determine which order arguments
were added in in some cases.

Do not sort SCEV objects by address: instead sort by complexity and group
by address.  This prevents the resultant SCEV objects from depending on
where in memory other scev objects happen to live.

Make use of BinaryOperator::create* methods to shrinkify code.

Add methods like BinaryOperator::createAdd that take an instruction to insert
before.

Fix the inliner to be deterministic, not letting its output depend on the
relative location of Function objects in memory.

Add some DEBUG output to the simplifycfg routines
Fix another non-deterministic behavior, this one should actually speed up the
code though as it was doing silly things.

A utility to search the LLVM source tree for a grep pattern. This is a
replacement for getsrcs.sh which now generates too much text to put on a
Linux command line. The approach taken with llvmgrep is to execute a find
command and execute a grep on each file that matches the name pattern. The
arguments to this script are the same as those of egrep. Note that the -H
and -n options to egrep will always be passed so that you always get the
file and line number of matches.

Now that dominator tree children are built in determinstic order, this horrible code
can go away

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@14254 91177308-0d34-0410-b5e6-96231b3b80d8

compute dominator tree children in a deterministic order that does not depend
on the address of BasicBlock objects in memory.  This eliminates stuff like this:

 Inorder Dominator Tree:
   [1]  %entry
     [2]  %loopentry
-      [3]  %loopexit
       [3]  %no_exit
-        [4]  %endif
         [4]  %then
+        [4]  %endif
+      [3]  %loopexit
       [3]  %return
