Nick Lewycky 42ded7042c This test is wrong. If you have two weak functions F and G you can't make 
either one call the other since either one can be replaced at link time, and
they need to be independent.

Nick Lewycky 3c6d34a7f0 Changes from Duncan's review: 
* merge two weak functions by making them both alias a third non-weak fn
 * don't reimplement CallSite::hasArgument
 * whitelist the safe linkage types

Nick Lewycky d01d42e76c Add a new MergeFunctions pass. It finds identical functions and merges them. 
This triggers only 60 times in llvm-test (look at .llvm.bc, not .linked.rbc)
and so it probably wont be turned on by default. Also, may of those are likely
to go away when PR2973 is fixed.
