PATCH for base_pool_allocator (PR other/81667)

[Marek Polacek <polacek@redhat.com>]

This PR points out that m_elt_size was left uninitialized in the member
initializer list for base_pool_allocator.  I think it makes sense to initialize
it like this.

Bootstrapped/regtested on x86_64-linux, ok for trunk?
