This is missing the synchronized_pool_resource and

This is a new implementation, not based on the existing code in
<experimental/memory_resource>, but memory_resource and
polymorphic_allocator ended up looking almost the same anyway.
The constant_init kluge in src/c++17/memory_resource.cc is apparently
due to Richard Smith and ensures that the objects are constructed during
constant initialiation phase and not destroyed (because the
constant_init destructor doesn't destroy the union member and the
storage is not reused).

Tested powerpc64le-linux, committed to trunk.
I missed a change to acinclude.m4 that should have gone with this
patch. Now also committed to trunk.
One of the tests also needs this fix.
And another correction to the same test.
Tested powerpc-ibm-aix7.2.0.0, committed to trunk.
