1c10a30949 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.

bf8c1cb6a3 add a check that allows the SRoA pass to avoid breaking programs, even if their 
behavior is technically undefined

ce23a1f169 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.

ab034e55b5 * 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.

91c5d68261 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.
