            Bug ID: 154903
           Summary: Vector<Attribute> in HTMLToken, AtomicHTMLToken, and
                    HTMLStackItem should have inline capacity
    Classification: Unclassified
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: HTML DOM
          Assignee: webkit-unassigned at lists.webkit.org

Vector<Attribute> in HTMLToken, AtomicHTMLToken, and HTMLStackItem are copied between each one of these objects.
We should set an inline capacity to make this cheap.

Using Apple's internal page loading tests, it seems like the inline capacity of four will cover 98% of the case:

000: 364295 (57.55%)
001: 151622 (23.95%)
002: 67306 (10.63%)
