9e89ba31f1 Rename AddReadAttrs to FunctionAttrs, and teach it how 
to work out (in a very simplistic way) which function
arguments (pointer arguments only) are only dereferenced
and so do not escape.  Mark such arguments 'nocapture'.

641397f2ef fix memory leak in pass manager when adding an analysis pass that already existed. as pass manager takes ownership of the added passes, it has to delete the pass if it isnt added to the pass list 
tweak the opt tool so that it doesnt access a Pass after the ownership was taken by the pass manager

0e3b7b2f91 Give GlobalsModRef a whirl in the nightly testers. 
I placed it just before GVN because that it is the
pass most likely to benefit from it.  Some quick
and dirty testing confirms that this is a decent
place for it.

fa191e4cd4 Run SimplifyLibCalls near the beginning, not at 
the end.  It is now run at the same moment as in
llvm-gcc.  Also, run StripDeadPrototypes at the
end, just before running DeadTypeElimination.
This may be useful when doing LTO.  Note that
llvm-gcc runs StripDeadPrototypes but not
DeadTypeElimination.
