We currently run these in swift-version 4 by default. This caused us to miss
some bugs that only occur in swift-version 5 due to initializer changes
happening in swift 5. This at least will allow us to catch such issues in the
future.
NOTE: I am also going to change objc_throwing_initializers.swift in the same
way, but after I fix the bugs that adding -swift-version 5 exposes therein
(which is actually <rdar://problem/59830255>)
change includes both the necessary protocol updates and the deprecation
warnings
suitable for migration. A future patch will remove the renamings and
make this
a hard error.
There's still work left to do. In terms of next steps, there's still rdar://problem/22126141, which covers removing the 'workaround' overloads for print (that prevent bogus overload resolution failures), as well as providing a decent diagnostic when users invoke print with 'appendNewline'.

Though the value may be statically known in some cases, that isn't good enough to do what we try to do with this information. In particular, if we invoke a class method on a MetatypeConversion, we want to dispatch to the method of the original metatype, not statically call the method of the converted type, which is what is evident in the AST. Fixes rdar://problem/18877135.

Inherited initializers are now functional: one can use an inherited
initializer to construct an object of a subclass type, and we properly
handle delegation to overridden complete object or subobject
initializers as appropriate. See the executable test.
This commit also contains various fixes for the IRGen side of vtable
emission and use. Proper IRGen tests still to come.
For now, we're still performing peer delegation from a subobject
initializer to another subobject initializer, hence the SILGen hack
for identifying when we're in a complete object vs. a subobject
initializer. We'll be banning delegation from subobject initializers,
so this hack---along with the peer_method instruction---will be going
away in the near future.
