1754e014f5 std.heap.SmpAllocator: rotate on free sometimes 
* slab length reduced to 64K
* track freelist length with u8s
* on free(), rotate if freelist length exceeds max_freelist_len

Prevents memory leakage in the scenario where one thread only allocates
and another thread only frees.

b3c63e5de0 Dwarf: fix cross_section_relocs capacity 
This ensure capacity call does not match the number of
appendAssumeCapacity() calls that follow it. Fix this.

This was discovered due to hitting the assertion failure in
appendAssumeCapacity() while building river.

I'm not sure how to isolate a minimal reproducer for a test.

bf7bc4ff01 langref/errorset: Replace subset description with union 
The previous language using subsets was really just stating a couple
of the properties of the union of a group of sets, and with a minor
error at that.

8626191549 std.heap.GeneralPurposeAllocator: fix slot_counts calculation 
In larger small buckets, the comptime logic that computed slot count did
not verify that the number it produced was valid. Now it verifies it,
which made this bug into a compile error. Then I fixed the bug by
introducing a "minimum slots per bucket" declaration.
