This is was a very mechanical patch where I basically first renamed SILNodes.def
and then just kept fixing things until everything compiled, so even though it is
large patch I feel ok(ish) with committing it.
If anyone has any concerns/etc, please email me and I will revert in 1 second.

We had a weird (and problematic for me) situation before where
tuple initializations would not recursively finalize their tuple
elements when they were finalized. Making them do so runs afoul
of the poorly named Initialization::getSubInitializations(x,y,z)
method, which had nothing to do with the
Initialization::getSubInitializations() method. Rename the former
to "getSubInitializationsForTuple" to make it more clear what is
going on, and make it handle the finalization of the SingleElement
initialization when it explodes it.
No functionality change, this unblocks some cases definite init was
tripping over.

Generate union constructors as SIL functions using the new 'union' instruction. Change UnionTypeInfo::emitInjectionFunctionBody into UnionTypeInfo::emitInjection, which emits the union value to an explosion rather than emitting the scalar return directly, and use it to implement IRGen lowering of the 'union' instruction.
This breaks a few serialization tests because of mangler bugs handling generic unions, which I'll fix next.

This is a baby step toward eliminating GenericParamList from
PolymorphicFunctionType, fixing up the easy callers. No functionality
change.
