CoroSplit: Fix coroutine splitting for retcon and retcon.once
Summary:
For retcon and retcon.once coroutines we assume that all uses of spills
can be sunk past coro.begin. This simplifies handling of instructions
that escape the address of an alloca.
The current implementation would have issues if the address of the
alloca is escaped before coro.begin. (It also has issues with casts before and
uses of those casts after the coro.begin instruction)
%alloca_addr = alloca ...
%escape = ptrtoint %alloca_addr
coro.begin
store %escape to %alloca_addr
