Reviewed by Sam Weinig.

Source/WebKit2:

* Configurations/BaseTarget.xcconfig: Defined HAVE_CORE_PREDICTION and added
  HAVE_CORE_PREDICTION to the preprocessor defintions when the former is YES.

* Configurations/WebKit.xcconfig: Have the linker link against CorePrediction where
  available. On macOS, use weak linking, because CorePrediction is not available in the
  Base System.

* Platform/classifier/cocoa/CorePredictionSoftLink.h: Removed.

* Platform/classifier/cocoa/ResourceLoadStatisticsClassifierCocoa.cpp: Guarded with
  #if HAVE(CORE_PREDICTION).
(WebKit::isNullFunctionPointer): Added this helper.
(WebKit::ResourceLoadStatisticsClassifierCocoa::canUseCorePrediction): Replaced
  dlopen()-based runtime check with a null check.

* Platform/classifier/cocoa/ResourceLoadStatisticsClassifierCocoa.h: Guarded with #if
  HAVE(CORE_PREDICTION).

* Platform/spi/Cocoa/CorePredictionSPI.h: Added.

* UIProcess/WebResourceLoadStatisticsStore.h: Updated guards to include HAVE(CORE_PREDICTION).

* WebKit2.xcodeproj/project.pbxproj: pdated file references for removal and addition.

WebKitLibraries:

* WebKitPrivateFrameworkStubs/iOS/10/CorePrediction.framework: Added this framework stub.
* WebKitPrivateFrameworkStubs/iOS/10/CorePrediction.framework/CorePrediction.tbd: Added.
