John McCall 5fb5df9c83 Restructure how the driver communicates information about the
target Objective-C runtime down to the frontend:  break this
down into a single target runtime kind and version, and compute
all the relevant information from that.  This makes it
relatively painless to add support for new runtimes to the
compiler.  Make the new -cc1 flag, -fobjc-runtime=blah-x.y.z,
available at the driver level as a better and more general
alternative to -fgnu-runtime and -fnext-runtime.  This new
concept of an Objective-C runtime also encompasses what we
were previously separating out as the "Objective-C ABI", so
fragile vs. non-fragile runtimes are now really modelled as
different kinds of runtime, paving the way for better overall
differentiation.

As a sort of special case, continue to accept the -cc1 flag
-fobjc-runtime-has-weak, as a sop to PLCompatibilityWeak.

I won't go so far as to say "no functionality change", even
ignoring the new driver flag, but subtle changes in driver
semantics are almost certainly not intended.

// There are basically four ways that we end up doing message dispatch for the
// NeXT runtime. They are:
// (1) fragile ABI, legacy dispatch
// (2) non-fragile ABI, legacy dispatch
// (2) non-fragile ABI, non-legacy dispatch
// (2) non-fragile ABI, mixed dispatch
//
// Note that fragile ABI and non-fragile ABI legacy dispatch are not the same,
// they use some different API calls (objc_msgSendSuper vs objc_msgSendSuper2).
