Eric Christopher 7a50b280c1 Add objectsize intrinsic and hook it up through codegen. Doesn't 
do anything than return "I don't know" at the moment.

Jeffrey Yasskin bf43f6543d Automatically do the equivalent of freeMachineCodeForFunction(F) when F is 
being destroyed. This allows users to run global optimizations like globaldce
even after some functions have been jitted.

This patch also removes the Function* parameter to
JITEventListener::NotifyFreeingMachineCode() since it can cause that to be
called when the Function is partially destroyed. This change will be even more
helpful later when I think we'll want to allow machine code to actually outlive
its Function.

Mike Stump 7a484dd6a9 Prep for future __builtin_object_size refinements. The theory is that 
someone will add an llvm intrinsic for us to use, so the optimizer can
figure out the hard cases.  WIP.

For those that want to help, double check with Eric before starting.
He has a bit of code this will plug into.

Dan Gohman 34e38afa96 Simplify this code. LoopDeletion doesn't need to explicit check that 
the loop exiting block dominates the latch block; if ScalarEvolution
can prove that the trip-count is finite, that's sufficient.

Dan Gohman 6a1d9eace9 Check in the experimental GEP splitter pass. This pass splits complex 
GEPs (more than one non-zero index) into simple GEPs (at most one
non-zero index).  In some simple experiments using this it's not
uncommon to see 3% overall code size wins, because it exposes
redundancies that can be eliminated, however it's tricky to use
because instcombine aggressively undoes the work that this pass does.

Dan Gohman 9aba0d9988 When checking whether a def of an aliased register is dead, ask the 
machineinstr whether the aliased register is dead, rather than the original
register is dead. This allows it to get the correct answer when examining
an instruction like this:
  CALLpcrel32 <ga:foo>, %AL<imp-def>, %EAX<imp-def,dead>
where EAX is dead but a subregister of it is still live. This fixes PR5294.
