Revert "Update LLVM bindings after r239940. ..."

Revert the changes to the C API LLVMBuildLandingPad that were part of
the personality function move. We now set the personality on the parent
function when the C API attempts to construct a landingpad with a
personality.

This reverts commit r240010.
