Subject: [PATCH] Fix GCC build: avoid default member initializers in
 PersistedBindingOverride

GCC rejects a nested type's default member initializers when a member
declaration of the enclosing class needs them before the class is
complete (gcc bug 96645) - here the robin_hood map member instantiates
std::array<PersistedBindingOverride, MAX_BINDINGS>'s default
constructor. Clang and MSVC both accept this. Initialize via the
constructor instead; semantics unchanged.
