[Linux] Enable Gigacage in x64 Linux environment
https://bugs.webkit.org/show_bug.cgi?id=177745
Reviewed by Carlos Garcia Campos.
This patch enables Gigacage in x64 Linux environment.
Gigacage enforces a caged pointer to reference to the
specific memory region. This reduces the effectiveness
of some types of attacks setting a pointer to ArrayBuffer
and modifying arbitrary memory region.
