For PR786:
...
Turn on -Wunused and -Wno-unused-parameter. Clean up most of the resulting
fall out by removing unused variables. Remaining warnings have to do with
unused functions (I didn't want to delete code without review) and unused
variables in generated code. Maintainers should clean up the remaining
issues when they see them. All changes pass DejaGnu tests and Olden.

Change the callgraph representation to store the callsite along with the

target CG node. This allows the inliner to properly update the callgraph
when using the pruning inliner. The pruning inliner may not copy over all
call sites from a callee to a caller, so the edges corresponding to those
call sites should not be copied over either.

Add a simple pass to make sure that all (non-library) calls to malloc and free

are visible to analysis as intrinsics. That is, make sure someone doesn't pass
free around by address in some struct (as happens in say 176.gcc).
This doesn't get rid of any indirect calls, just ensure calls to free and malloc
are always direct.

that lives the full life of the compiler.
