Web Inspector: Fix multiple console.assert stripping issues

• Component: Web Inspector
• Status: RESOLVED FIXED

[Joseph Pecoraro]

- one console.assert missing semicolon, assumed to be multi-line, not stripped
- one console.assert inside of a for loop without braces, results in following line accidentally looping!

I plan on adding a WARNING to catch the second error.

[Joseph Pecoraro]

With the new warning, and a script to process each JS file of ours, this is the output I see:

    shell> ./Scripts/remove-console-asserts-dryrun.rb 
    DOMTreeManager.js:
    WARNING: console.assert inside control flow statement without braces on line: 556:             console.assert(contentFlow.contentNodes[i].id === flowPayload.content[i]);

    DataGrid.js:
    WARNING: Multi-line console.assert on line 775:         console.assert(!child.isPlaceholderNode, "Shouldn't delete the placeholder node.")

[Joseph Pecoraro]

If the line ends in a ')' then its likely not multi-line and just a missing semicolon. Changed that warning to:

    DataGrid.js:
    WARNING: console.assert missing trailing semicolon on line 775:         console.assert(!child.isPlaceholderNode, "Shouldn't delete the placeholder node.")
