DFG inlining sometimes fails to reset constant references https://bugs.webkit.org/show_bug.cgi?id=70668 Source/JavaScriptCore: Reviewed by Anders Carlsson. Reset constant references when we need to (new block created) and not when we don't (change of inlining depth). * dfg/DFGByteCodeParser.cpp: (JSC::DFG::ByteCodeParser::handleInlining): (JSC::DFG::ByteCodeParser::prepareToParseBlock): (JSC::DFG::ByteCodeParser::parseBlock): (JSC::DFG::ByteCodeParser::parseCodeBlock): LayoutTests: Reviewed by Anders Carlsson. Added a new test that covers this specific bug as well as the general ability to perform inlining, and the ability to OSR out of an inline stack. * fast/js/dfg-inline-constant-expected.txt: Added. * fast/js/dfg-inline-constant.html: Added. * fast/js/script-tests/dfg-inline-constant.js: Added.

This tests that function inlining in the DFG JIT doesn't get confused by constants being reused between inliner and inlinee.
