Some tests fail with YARR interpreter since r67790 (https://bugs.webkit.org/show_bug.cgi?id=45787):

ecma_2/RegExp/exec-002.js
ecma_3/RegExp/octal-001.js
ecma_3/RegExp/perlstress-002.js
ecma_3/RegExp/regress-103087.js
ecma_3/RegExp/regress-165353.js
ecma_3/RegExp/regress-169497.js
ecma_3/RegExp/regress-191479.js
ecma_3/RegExp/regress-216591.js
ecma_3/RegExp/regress-24712.js
ecma_3/RegExp/regress-85721.js
js1_2/regexp/everything.js
js1_2/regexp/interval.js
js1_2/regexp/regress-9141.js

13 regressions found.

These tests terminate by segmentation fault.

I don't fully investigate the a problem yet but I think it is caused 
by the patch of the "Yarr JIT code checks BOL (^) each time through loop when in subexpression" bug.

I created a simple testcase too:
"a".match(/((a)*)/);
