Yuta Saito b5ae4d1397 [IRGen] Emit keypath thunk helpers with swiftcc to match the caller cc ...

KeyPath thunk helpers are called from stdlib indirectly through
descriptor and its calling-convention in the caller side is SwiftCC.
However, the definition side expects C calling-convention, so they
can be broken on some architectures, that SwiftCC is not compatible
with C-CC on it.

This patch changes to use SwiftCC consistently on caller side and
definition side.
This doesn't have any effect on the ABI stable platforms because
SwiftCC is compatible with C-CC on them.
