Gor Nishanov 91fe7677db [Coroutines] Part13: Handle single edge PHINodes across suspends

Summary:
If one of the uses of the value is a single edge PHINode, handle it.

Original:

    %val = something
    <suspend>
    %p = PHINode [%val]

After Spill + Part13:

    %val = something
    %slot = gep val.spill.slot
    store %val, %slot
    <suspend>
    %p = load %slot

Plus tiny fixes/changes:
   * use correct index for coro.free in CoroCleanup
   * fixup id parameter in coro.free to allow authoring coroutine in plain C with __builtins
