libstdc++: Remove some more unconditional uses of atomics
These atomics cause linker errors on arm4t where __sync_synchronize is
not defined. For single-threaded targets we don't need the atomics.
libstdc++-v3/ChangeLog:
* include/experimental/io_context (io_context) [!_GLIBCXX_HAS_GTHREADS]:
Use a plain integer for _M_work_count for single-threaded
targets.
* include/experimental/memory_resource (__get_default_resource)
[!_GLIBCXX_HAS_GTHREADS]: Use unsynchronized type for
single-threaded targets.
* src/c++17/default_resource.h: Adjust preprocessor conditions
to match memory_resource.cc.
* src/c++17/memory_resource.cc [!_GLIBCXX_HAS_GTHREADS]
(atomic_mem_res): Use unsynchronized type for single-threaded
targets.
