https://bugs.webkit.org/show_bug.cgi?id=68500 Reviewed by Oliver Hunt. This adds support for compiling constructors to the DFG. It's a 1% speed-up on V8, mostly due to a 6% speed-up on early-boyer. It's also a 13% win on access-binary-trees, but it's neutral in the SunSpider and Kraken averages. * dfg/DFGByteCodeParser.cpp: (JSC::DFG::ByteCodeParser::parseBlock): * dfg/DFGCapabilities.h: (JSC::DFG::mightCompileFunctionForConstruct): (JSC::DFG::canCompileOpcode): * dfg/DFGNode.h: * dfg/DFGOperations.cpp: * dfg/DFGOperations.h: * dfg/DFGPropagator.cpp: (JSC::DFG::Propagator::propagateNodePredictions): (JSC::DFG::Propagator::performNodeCSE): * dfg/DFGSpeculativeJIT.cpp: (JSC::DFG::SpeculativeJIT::compile): * runtime/Executable.cpp: (JSC::FunctionExecutable::compileOptimizedForConstruct): (JSC::FunctionExecutable::compileForConstructInternal): * runtime/Executable.h: (JSC::FunctionExecutable::compileForConstruct): (JSC::FunctionExecutable::compileFor): (JSC::FunctionExecutable::compileOptimizedFor): git-svn-id: http://svn.webkit.org/repository/webkit/trunk@95672 268f45cc-cd09-0410-ab3c-d52691b4dbfc
