[CMake] build-webkit should be able to enable address sanitizer

[Michael Catanzaro]

If I have run 'set-webkit-configuration --asan' then build-webkit should pass -DENABLE_ADDRESS_SANITIZER=ON to CMake, so it actually does something.

Do we already support ASan building with CMake using script build-jsc? If not, we should fix this up.

It is unnecessary to call this. We should call asanIsEnabled() on the line below (notice it is a function call).

We did not, but build-jsc uses buildCMakeProjectOrExit(), which calls generateBuildSystemFromCMakeProject(), which is the function I'm modifying here, so now it will.
