process.  The only optimization we did so far is to avoid creating a
PHI node, then immediately destroying it in the common case where the
callee has one return statement.  Instead, we just don't create the return
value.  This has no noticable performance impact, but paves the way for
future improvements.

to add the cloned block to.  This allows the block to be added to the function
immediately, and all of the instructions to be immediately added to the function
symbol table, which speeds up the inliner from 3.7 -> 3.38s on the PR209.

0.62s on the testcase from PR209.

because we now create constantexprs for the constants instead of failing the
fold.

* Implement SCCP of load instructions, implementing Transforms/SCCP/loadtest.ll
  This allows us to fold expressions like "foo"[2], even if the pointer is only
  a conditional constant.

Fix iterator invalidation problems which was causing -mstrip to miss some
