setSelectionRange shouldn't trigger a synchronous layout to check focusability when text field is already focused

• Component: Forms
• Status: RESOLVED FIXED

[Ryosuke Niwa]

HTMLTextFormControl::setSelectionRange doesn't need to trigger a synchronous layout
if the text field is already focused since we don't need to call hasVisibleTextArea in that case,
which depends on the dimension of RenderBox.

[Ryosuke Niwa]

We can get rid of synchronous layout completely once we fix webkit.org/b/38696 as I've outlined in
https://lists.webkit.org/pipermail/webkit-dev/2014-February/026235.html

but we can fix this one first in order to resolve the bug 128797 since we don't call setSelectionRange in setValue when the text field is not focused.

Odd. I thought I removed this tab character before uploading it :/
