<h3>Log Message</h3>
<pre>DumpRenderTree should stop using CheckedMalloc.
https://bugs.webkit.org/show_bug.cgi?id=165563
<rdar://problem/28945820>
Reviewed by Geoffrey Garen.
1. WebKitTestRunner does not have equivalent behavior to that which is implemented
in CheckedMalloc.
2. bmalloc does not honor the settings of CheckedMalloc.
The only time CheckedMalloc comes into play is when DRT uses gmalloc or system
malloc. As a result, DRT exhibits different behavior from the normal way we run
our tests. We should obsolete CheckedMalloc and make DRT behave consistently
with WKTR.
