a64cc5562f Remove indirection in the common case. 
Rather than unconditionally storing a pointer to the pagemap and
initialising this with a global, we now provide a choice of three
compile-time options for how the pagemap should be accessed.

c673926d15 Add missing const. 
No idea why this only raised an error with cl.exe, it was wrong on all
platforms.

d0fefb8641 Don't always refer to the global pagemap. 
If you're creating a new allocator and the pagemap comes from a library
that exports the pagemap accessor function but not the pagemap symbol,
you need to be able to replace this.

a93f43fd2f Add some type safety to other pagemap accesses.

descriptor is compatible with the destination type.

869b22b422 Sort test order so that perf tests start first. 
These take longer, so we want to start them earlier and let the shorter
tests fill in the gaps in scheduling.

11ccf365d3 Move LD_PRELOAD to a separate test. 
The Linux Debug build is currently one of the slowest two, pull out one
phase of it that is independent and allow it to run in parallel with the
other tests.

ef50a0282b Attempt to make CI faster. 
- Don't run an expensive functionality test in debug builds.
- Don't run the different cache configurations (they're probably going
  away soon because they help only in synthetic benchmarks).

6a5359b177 Pull aligned allocation out of the PAL. 
The PAL can now advertise that it supports aligned allocation.  If it
does not, then the memory provider will do the alignment for it.

This change still leaves the PAL responsible for systematic testing, but
it should now be much easier to lift that out.

01bd77b356 Remove some ugly templated things. 
Replace them with some very simple constexpr things.  This is what the
code used to look like, but it appears that I fundamentally
misunderstood why it didn't work.  This version should be a lot more
maintainable.

f178028640 [NFC] clang-format again. 
It appears that clang-format 6 (which CI uses) removes a newline that
clang-format 7 doesn't, but will also not add.  The new formatting
should keep 6 and 7 both happy.

80630a359f Clean up interface to the low memory notifications. 
- Rename MemoryProviderState to PAL to reflect what is now is.
 - Hide calls to the PAL's low memory functions behind something that
   returns a default value if they're not implemented.

6af4c97726 Explicitly qualify a method.

method name, clang rejects it.  Both accept the qualified name.

66cec23b23 Initial cut at a lazy decommit strategy. 
This does not deallocate memory until the OS tells us that we are short
on memory, then tries to decommit all of the cached chunks (except for
the first page, used for the linked lists).

Nowhere near enough testing to commit to master yet!
