Since they do not present the same structural interface, they should be
separate types (i.e., hasMember cannot tell the difference between a
'shared' method and a thread-local method).
SharedRegion will now always assume that its ParentAllocator is a real
allocator, and attempt to use its 'allocate' and 'deallocate' methods
accordingly.
The behavior previously provided by SharedRegion!(NullAllocator, ...)
remains available via shared(BorrowedRegion!(...)).
See issue 23090 for detailed rationale.

Previously, this behavior could only be obtained by instantiating Region
with NullAllocator as its ParentAllocator. Extracting it into a separate
allocator will allow Region itself to be simplified.
The emplace() stuff was moved to druntime; for some reason, it's still
in Phobos.
I've diffed the two versions, and they are still almost identical (incl.
unittests); the druntime version appears to have seen some improvements
(e.g., forwarding r/lvalueness of the arguments) in the meantime.
Nothing else in druntime/Phobos uses the problematic `minimumPageSize`
symbol. Problematic because the page size changes from 4 to 16 KB with
macOS 11.0.
It was unable to handle alignments > 2^31 bytes, e.g., returning 2 for
the 64-bit pointer 0x2FA_00000000. Return a size_t instead of a uint.
Note that it's only called in one place, an assertion in a ctor of the
BitmappedBlockImpl mixin, which handles size_t fine.
This fixes sporadic
std.experimental.allocator.building_blocks.bitmapped_block unittest
failures for LDC CI on Win64 (something like 1 out of 100 runs failing).
* Trim as much version(unittest) as possible from allocator
* improve internal test function addr to m_addr (and fix verbosity a bit)
* Remove shared from RCISharedAllocator, as it's already shared
* Fix issue with m_addr
