Avoid increasing required alignment of target type warning on ARM
​https://bugs.webkit.org/show_bug.cgi?id=38045

The reinterpret_cast<Type1*>([pointer to Type2]) expressions - where
sizeof(Type1) > sizeof(Type2) - cause the following warning on ARM:
increases required alignment of target type warnings.
Casting the type of [pointer to Type2] object to void* bypasses the
warning.
