Reviewed by Brian Burg.

Source/JavaScriptCore:

• debugger/Debugger.h:

(JSC::Debugger::Client::scopeExtensionObject): Added.

• debugger/Debugger.cpp:

(JSC::Debugger::setClient): Added.
(JSC::Debugger::evaluateBreakpointCondition):
(JSC::Debugger::evaluateBreakpointActions):
Introduce an optional Debugger::Client virtual class that can be used to adjust behavior
in various situations. Right now it is used when evaluating breakpoint conditions/actions
to get a scope extension object.

• inspector/agents/InspectorDebuggerAgent.h:
• inspector/agents/InspectorDebuggerAgent.cpp:

(Inspector::InspectorDebuggerAgent::internalEnable):
(Inspector::InspectorDebuggerAgent::internalDisable):
(Inspector::InspectorDebuggerAgent::scopeExtensionObject): Added.
Implement Debugger::Client and provide a newly created CommandLineAPI instance.

• inspector/InjectedScript.h:
• inspector/InjectedScript.cpp:

(Inspector::InjectedScript::createCommandLineAPIObject const): Added.

• inspector/InjectedScriptSource.js:

(let.InjectedScript.prototype.createCommandLineAPIObject): Added.
(let.InjectedScript.prototype._evaluateOn):
Expose a way for the C++ to create CommandLineAPI instances.

Source/WebInspectorUI:

• UserInterface/Controllers/CodeMirrorCompletionController.js:

(WI.CodeMirrorCompletionController):
(WI.CodeMirrorCompletionController.prototype.get mode): Added.
(WI.CodeMirrorCompletionController.prototype.get delegate): Deleted.

• UserInterface/Controllers/JavaScriptRuntimeCompletionProvider.js:

(WI.JavaScriptRuntimeCompletionProvider.prototype.completionControllerCompletionsNeeded):
(WI.JavaScriptRuntimeCompletionProvider.prototype.completionControllerCompletionsNeeded.shouldExposeEvent): Added.
(WI.JavaScriptRuntimeCompletionProvider.prototype.completionControllerCompletionsNeeded.shouldExposeException): Added.
(WI.JavaScriptRuntimeCompletionProvider.prototype.completionControllerCompletionsNeeded.receivedPropertyNames):
Introduce a Mode enum that can be fetched by completion providers to adjust functionality.

• UserInterface/Views/BreakpointPopover.js:

(WI.BreakpointPopover.appendContextMenuItems):
(WI.BreakpointPopover.prototype.show):
(WI.BreakpointPopover.prototype.breakpointActionViewCodeMirrorCompletionControllerMode): Added.
(WI.BreakpointPopover.prototype.get codeMirrorCompletionControllerMode): Added.

• UserInterface/Views/EventBreakpointPopover.js:

(WI.EventBreakpointPopover.prototype.get codeMirrorCompletionControllerMode): Added.

• UserInterface/Views/BreakpointActionView.js:

(WI.BreakpointActionView.prototype._updateBody):
Use a Mode that always exposes $event/$exception depending on the breakpoint type.

• UserInterface/Views/ConsolePrompt.js:

(WI.ConsolePrompt):
Use a Mode that only exposes $event/$exception when paused for an event/exeption.

• UserInterface/Views/ScopeChainDetailsSidebarPanel.js:

(WI.ScopeChainDetailsSidebarPanel.prototype._addWatchExpressionButtonClicked):
Use a Mode that always exposes $event/$exception since watch expressions track values
over time, and may therefore not always have an $event/$exception set.

• UserInterface/Views/TextEditor.js:

(WI.TextEditor):
Use the default Mode that never exposes $event/$exception.
