For each loop, keep track of all the IV expressions inserted indexed by
stride. For a set of uses of the IV of a stride which is a multiple

previous IV and rewrite the uses as uses of IV expression multiplied by
the factor.

e.g.

This implements Reassociate/mul-factor3.ll

Promote shifts by a constant to multiplies so that we can reassociate
(x<<1)+(y<<1) -> (X+Y)<<1.  This implements

Allow a sequence of digits at the end of the directory name when trying to
determine the top directory. This allows the tool to find the correct top
directory when you have something like:

   /x/llvm
   /x/llvm2
   /x/llvm3

Previously the scripts would always find /x/llvm even if you were in the
llvm2 or llvm3 directory because the pattern didn't allow the digits at
the end of the path.
