+PIC Code Gen IPO optimization:

+Squish small scalar globals together into a single global struct, allowing the 
+address of the struct to be CSE'd, avoiding PIC accesses (also reduces the size
+of the GOT on targets with one).

+Note that this is discussed here for GCC:

 Implement Newton-Rhapson method for improving estimate instructions to the
 correct accuracy, and implementing divide as multiply by reciprocal when it has
 more than one use.  Itanium will want this too.
