27f29e424b LQ_QUANTUM should be 4 on mips64 hardware.
This matches the ABI stack alignment requirements.

eda9c2858f Edata: zero stack edatas before initializing.
This avoids some UB. No compilers take advantage of it for now, but no sense in
tempting fate.

5dead37a9d Allow narenas:default.
This can be useful when you know you want to override some lower-priority
configuration setting with its default value, but don't know what that value
would be.

The prof inline functions are no longer involved in a circular

f1f8a75496 Let opt.zero propagate to core allocation.
I.e. set dopts->zero early on if opt.zero is true, rather than leaving it set by
the entry-point function (malloc, calloc, etc.) and then memsetting.  This
avoids situations where we zero once in the large-alloc pathway and then again
via memset.

79dd0c04ed SC: Simplify SC_NPSIZES computation.
Rather than taking all the sizes and subtracting out those that don't fit, we
instead just add up all the ones that do.

4f8efba824 TSD: Make rtree_ctx a slow-path field.
Performance-sensitive users will use sized deallocation facilities, so that
actually touching the rtree_ctx is unnecessary.  We make it the last element of
the slow data, so that it is for practical purposes almost-fast.

40e7aed59e TSD: Move in some of the tcache fields.
We had put these in the tcache for cache optimization reasons.  After the
previous diff, these no longer apply.

3589571bfd SC: use SC_LG_NGROUP instead of its value.
This magic constant introduces inconsistencies.  We should be able to change its
value solely by adjusting the definition in the header.

a4759a1911 Ehooks: avoid touching arena_emap_global in tests.

1a1124462e PA: Take zero as a bool rather than as a bool *.
Now that we've moved junking to a higher level of the allocation stack, we don't
care about this performance optimization (which only occurred in debug modes).

294b276fc7 PA: Parameterize emap. Move emap_global to arena.
This lets us test the PA module without interfering with the global emap used by
the real allocator (the one not under test).
