-----------
HashTable should allow alignof(ValueType) to be 32
https://bugs.webkit.org/show_bug.cgi?id=275097
Reviewed by Darin Adler.
HashTable has been assuming that alignof(ValueType) will never exceed 16 (i.e.
`4 * sizeof(unsigned)`),
but PlayStation is seeing 32 for alignof(std::function<T>), meaning that
ResourceUsageThread::m_observers
causes us to hit the static_assert in HashTable::allocateTable. We are
investigating the background of this
alignof value, but regardless, it should still be possible to allocate a
HashTable under these circumstances.
* Source/WTF/wtf/HashTable.h:
Let metadataSize be larger than `4 * sizeof(unsigned)` when necessary,
so as to preserve the invariant `metadataSize % alignof(ValueType) == 0`.
