Sanjoy Das 9abfb0b429 Use WeakVH to keep track of calls with operand bundles in CloneCodeInfo 
`CloneAndPruneIntoFromInst` can DCE instructions after cloning them into
the new function, and so an AssertingVH is too strong.  This change
switches CloneCodeInfo to use a std::vector<WeakVH>.

Sanjoy Das b8dced5dfa Don't drop attributes when inlining through "deopt" operand bundles 
Test case attached (test case also checks that we don't drop the calling
convention, but that functionality was correct before this patch).

Sanjoy Das 2d16145acf Teach the inliner to track deoptimization state 
Summary:
This change teaches LLVM's inliner to track and suitably adjust
deoptimization state (tracked via deoptimization operand bundles) as it
inlines through call sites.  The operation is described in more detail
in the LangRef changes.
