Summary: Make improvements to Type Profiling
Product: WebKit
Version: 528+ (Nightly build)
Platform: Unspecified
OS/Version: Unspecified
Status: NEW
Severity: Normal
Priority: P2
Component: JavaScriptCore
AssignedTo: webkit-unassigned at lists.webkit.org
ReportedBy: sbarati at apple.com

This diff almost completes the patch I want to submit to make significant improvements to the infrastructure around profiling types in JSC.
- We now know which functions have executed.
- Ranges have been made to be zero indexed, because this is simply how it should be.
- There are fewer extraneous methods that weren't needed.
- The inspector no longer receives a String blob from JSC, it now gets back structured data.
- Constructor names are now gathered for Objects
(There is also corresponding code in this current diff that shows some WebInspector JavaScript files that support displaying types, but this is there simply to show the start of code on that side, it will not make it into this patch. It will be made into a different patch under the WebInspector)
