Make this pass substantially stronger by having it delete dead return values
...
as well as arguments. Now it can delete arguments and return values which are
only passed into other arguments or are returned, if they are dead. This causes
it to delete several hundred extra args/retvals from the C++ hello world program,
shrinking it by about 2K.

Preselection is _not_ a basicblock pass, because it adds global variables to

the module. This change converts it from being a basic block pass to being
a simple pass. This allows elimination of the annotation and simplification
of the logic for moving constants into global variables.
