$vm should have a function for checking if ASan is enabled similar to $vm.assertEnabled
https://bugs.webkit.org/show_bug.cgi?id=226019
Patch by Tuomas Karkkainen <[email protected]> on 2021-05-20
Reviewed by Mark Lam.
Add method $vm.asanEnabled(), which parallels $vm.assertEnabled(), and allows checking at
runtime whether the current _javascript_Core build is instrumented with AddressSanitizer.
