Alex Lorenz d2677c8ed5 [compiler-rt][builtins] Ignore the deprecated warning for 
CFPropertyListCreateFromXMLData that's used in __isOSVersionAtLeast

I forgot to add the pragmas in r297760.

Alex Lorenz ca1fab5d66 [compiler-rt][builtins] __isOSVersionAtLeast should load CoreFoundation 
symbols dynamically

The CoreFoundation symbols uses by __isOSVersionAtLeast should be loaded at
runtime to ensure that the programs that don't use @available won't have to be
linked to CoreFoundation.

The Clang frontend IRGen library will need to emit a CoreFoundation symbol
when @available is used to ensure that programs that actually use @available
are linked to CoreFoundation.

Erik Pilkington 0490e1c5f4 Reapply r297382: "[compiler-rt][builtins] Add __isOSVersionAtLeast()" 
Looks like the problem was a case-insensitive include of dispatch/dispatch.h.

Erik Pilkington 4d297df95c Revert "[compiler-rt][builtins] Add __isOSVersionAtLeast()" 
This reverts r297382, it was causing build failures.

Erik Pilkington 6fa97926e9 [compiler-rt][builtins] Add __isOSVersionAtLeast() 
This predicate compares the host's marketing OS version to one passed as
argument. Currently, only darwin targets are supported. This is done by parsing
the SystemVersion.plist file.

Also added in this patch is some lit testing infrastructure for builtins, which
previously had none. This part of the patch was written by Alex Lorenz (with
some minor modifications).

This patch is part of a feature I proposed here:
