b37923f9a1 Okay totally give up on trying to optimize aggregates that cannot be completely
broken up into their elements.  Too many programs break because of this.

26d2ca1d13 add a check that allows the SRoA pass to avoid breaking programs, even if their
behavior is technically undefined

6074d2f37a Added the CloneTrace function which clones traces. It takes a vector of basic blocks, removes
internal phi nodes, and returns a new vector of basic blocks.

2345d71853 * Revert to old behavior of ignoring a module if it doesn't contain a main
function and no symbols were explicitly marked to be externalized.
* Add new -internalize-public-api-list option that can be used if the symbol
  list is small, and making a new file is annoying.

c54e2b8f84 Minor cleanups.
This hunk:
-    } else if (Src->getNumOperands() == 2 && Src->use_size() == 1) {
+    } else if (Src->getNumOperands() == 2) {

Allows GEP folding to be more aggressive, which reduces the number of instructions
and can dramatically speed up BasicAA in some cases.

  * Functions could not be resolved unless they had external linkage.  Linkonce

  * ConstantPointerRef's were not handled when linking functions
    we now actually handle cast (CPR) to X -> cast (NewCPR) to X
