Message:

Make CLoop easier to build, and make it work
​https://bugs.webkit.org/show_bug.cgi?id=124359

Reviewed by Geoffrey Garen.

Source/JavaScriptCore:

Add --cloop to build-jsc, build-webkit and friends.

Also make CLoop build and work again - This meant adding a
couple of missing ENABLE(DFG_JIT) blocks, and fixing a few
other references.

• Configurations/FeatureDefines.xcconfig:
• bytecode/BytecodeLivenessAnalysis.cpp:

(JSC::computeUsesForBytecodeOffset):
(JSC::computeDefsForBytecodeOffset):

• dfg/DFGCapabilities.cpp:
• dfg/DFGCompilationKey.cpp:
• dfg/DFGCompilationMode.cpp:
• jit/JITExceptions.cpp:

(JSC::genericUnwind):

Source/WebCore:

Add cloop configuration info to WebCore FeatureDefines
so that it's consistent with JSC

• Configurations/FeatureDefines.xcconfig:

Source/WTF:

Make building with the CLoop forcibly enabled manually
disable the JITs

• wtf/Platform.h:

Tools:

Add --cloop support to forcibly enable to CLoop build
