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

call malloc/free. This fixes PR555.

using Function::arg_{iterator|begin|end}. Likewise Module::g* -> Module::global_*.

Actually overload the virtual method. This fixes

Regression/Analysis/GlobalsModRef/purecse.ll. Isn't this what the
-Woverload-whatever flag would warn about :)

'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.

public header files must be under include/llvm/.

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.
