Create applies with the transparent bit set properly during devirtualization.

Fixes rdar://problem/19477863.

Again, no real perf diff here, probably because the next round of
inlining was already inlining these (most of the hits are on setters,
getters, etc. which tend to be quite small).

Having this fixed will be useful in a future where we do some trivial
devirtualization during inlining, in particular mandatory
inlining (rdar://problem/19418937).
