Daniel Paoliello 24ad32b97c [Coroutine] Split PHI Nodes in cleanuppad blocks in a way that obeys EH pad rules ... Issue Details: In order to support coroutine splitting, any multi-value PHI node in a coroutine is split into multiple blocks with single-value PHI Nodes, which then allows a subsequent transform to generate `reload` instructions as required (i.e., to reload the value if required if the coroutine has been resumed). This causes issues with EH pads (`catchswitch` and `catchpad`) as all pads within a `catchswitch` must have the same unwind destination, but the coroutine splitting logic may modify them to each have a unique unwind destination if there is a PHI node in the unwind `cleanuppad` that is set from values in the `catchswitch` and `cleanuppad` blocks. Fix Details: During splitting, if such a PHI node is detected, then create a "dispatcher" `cleanuppad` as well as the blocks with single-value PHI Nodes: thus the "dispatcher" is the unwind destination and it will detect which predecessor called it and then branch to the appropriate single-value PHI node block, which will then branch back to the original `cleanuppad` block.
