Malloc/Free have mod/ref effects. Do not allow CSE of function calls that

call malloc/free. This fixes PR555.

This mega patch converts us from using Function::a{iterator|begin|end} to
...
using Function::arg_{iterator|begin|end}. Likewise Module::g* -> Module::global_*.

'Pass' should now not be derived from by clients. Instead, they should derive

from ModulePass. Instead of implementing Pass::run, then should implement
ModulePass::runOnModule.

Fix conservative assumption, which was quite broken. Also, notice that

functions known to not access memory (like sin/cos) don't access memory! :)

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.
