The dir should be as the other script expects in https://bugs.webkit.org/show_bug.cgi?id=84330
methodcoverage --> methodcoverage/results

Additionally we should create this directory if it doesn't exist.

But I still get the following linking error:

Instrumenter::init() and Instrumenter::destroy() are in the libwebkit1.a,
but they aren't in the libQtWebKitWidgets.so for some reason ...

Here is the linking command of libQtWebKitWidgets.so:

It contains ... -Wl,-whole-archive -lWebKit1 -Wl,-no-whole-archive ...
How is it possible if the ld doesn't add everything to the so?

I moved the instrumenter from WebKit1 to DRT and it works now.
