932ddc328c logalloc: optimize current_allocation_strategy()
This heavily used function shows up in many places in the profile (as part
of other functions), so it's worth optimizing by eliminating the special
case for the standard allocator.  Use a statically allocated object instead.

(a non-thread-local object is fine since it has no data members).

5dc58a7cd4 allocation_strategy: Leak the standard strategy
Some code may attempt to use it during finalization after "instance"
was destroyed.

Reported by Pekka:
