It's a bit unfortunate that this is defined in a different file.  Maybe it
should be defined in test_shell.gypi instead?

I'm not sure I see much advantage to putting it here rather than in webkit.gyp;
the target is referenced from other files as well (see chrome_tests.gypi). If it
was only used/needed by test_shell I would agree, but for now it seems better to
keep it next to the other pull_in_* targets. 

Also, if I moved that target here I'd have to have
build_webkit_exes_from_webkit_gyp logic in two places. If you still want me to
move the target here, can it wait until when I delete the conditional logic from
common.gypi and webkit.gyp, and I can move it then?

chrome_tests.gypi is different, it explicitly names webkit.gyp.  If we wanted to
build test_shell in an upstream only checkout, this wouldn't work because we
don't include webkit.gyp in an upstream checkout (only webkit_support.gyp).

Anyway, this is fine for now, just a bit unfortunate.  We can refactor later if
we need to.
