Valgrind output when running HTML/JS test

This is Valgrind output when running the HTML/JS `test.html` attached earlier.  This is run on a recent WebKit mainline on x86_64 WPE build.

* Copy `test.html` into `./WebKitBuild/WPE/Debug/`

* Run the following

  WEBKIT_MINI_BROWSER_PREFIX="valgrind --trace-children=yes --trace-children-skip=WPENetworkProcess --read-var-info=yes --track-origins=yes --log-file=/app/webkit/WebKitBuild/Debug/valgrind-html.log " \
  JSC_forceRAMSize=1G JSC_logGC=2 JSC_numberOfGCMarkers=2 \
  ./Tools/Scripts/run-minibrowser --wpe --debug -- \
  --platform=headless --webprocess-failure=exit \
  file:///app/webkit/WebKitBuild/Debug/test.html

Again, `JSC_forceRAMSize=1G` and other flags are unlikely making any difference.  They are preserved though to make it more representative of the platform where the crash is reproduced.
