Fix conservative assumption, which was quite broken. Also, notice that
functions known to not access memory (like sin/cos) don't access memory! :)

Complete rewrite of this pass to be faster, use less memory, be easier to
understand, and more accurate to boot! This implements
GlobalModRef/purecse.ll over the previous impl.

Initial checkin of a simple mod/ref analysis for global variables. This is
still overly conservative and uses very simple data structures, but it is a
start, and allows elimination of a lot of loads.
