API tests started failing in the interval [r261537-r261541] (See: https://build.webkit.org/builders/GTK%20Linux%2064-bit%20Release%20(Tests)?numbuilds=50). The EWS API-GTK bot reported the tests were failing on r261538 (https://bugs.webkit.org/show_bug.cgi?id=211729) (https://ews-build.webkit.org/#/builders/34/builds/9068). So it was either r261537 or r261538. I run the API tests on r261537 and the tests run fine (only 1 unexpected timeout and 1 unexpected pass), so the regression was introduced in r261538.

By then, it is too late Missing some text here. I meant to say we were calling Wasm::enableFastMemory() in WebProcess::initializeWebProcess().

Diego has tested the patch manually and confirmed that it resolved the API test failures on GTK. I will land it shortly.
Landed in r261549: <http://trac.webkit.org/r261549>.
