When setting a willSet/didSet param's type, also set the TypeLoc (#7377)

We don't actually need the TypeLoc for anything, but it was still
getting type-checked, which means it doesn't get the benefit of
inference from the initial value. In some cases the actual type of the
ParamDecl seems to get reset to the TypeLoc's type as well. Just do
the simple thing and set it directly ahead of time.

Fixes a source compatibility issue with Swift 3.0.
