This broke the Apple Sierra Release 32-bit build, which builds without Touch Bar support:

[[
release/build/Source/WebKit2/UIProcess/Cocoa/WebViewImpl.mm:2991:6: error: use of undeclared identifier 'candidateListTouchBarItem'
    [candidateListTouchBarItem() setCandidates:candidates forSelectedRange:selectedRange inString:postLayoutData.paragraphContextForCandidateRequest rect:offsetSelectionRect view:m_view completionHandler:nil];
     ^
]]

Committed build fix in <https://trac.webkit.org/changeset/210245>.

We should look to extract out the Touch Bar code from Source/WebKit2/UIProcess/Cocoa/WebViewImpl.mm or at least consolidate it at one end of this file. Currently the Touch Bar code is scattered throughout this file and in #if/else chunks that are many lines long. As demonstrated by the Apple Sierra Release 32-bit build failure (comment #3) it is easy to lose track of what chunk in the file is HAVE(TOUCH_BAR)-guarded or not. I needed to use an editor that supports collapsing code regions in order to be able to track the #if HAVE(TOUCH_BAR) and #else chunks. This significantly affects the hackability of this file and makes refactoring code in it error prone.

Committed another attempt to fix the Apple Sierra Release 32-bit build in <https://trac.webkit.org/changeset/210247>.

We need to update Xcode on this bot; I don't think that this is a supported configuration any more.

Ryan took care of updating it.
