    • Avoid nonconst memmodels in libitm's local outdated copy of <atomic> too · b01819be 
      This avoids warnings in libitm for non constant memory models,
fixing the bootstrap with -Werror

Passed bootstrap and test on x86_64-linux.

	* local_atomic (__always_inline): Add.
	(__calculate_memory_order, atomic_thread_fence,
	 atomic_signal_fence, test_and_set, clear, store, load,
         exchange, compare_exchange_weak, compare_exchange_strong,
         fetch_add, fetch_sub, fetch_and, fetch_or, fetch_xor):
	Add __always_inline to force inlining.

    • Avoid non constant memory model uses in libatomic · 94f3ccc8 
      x86 ends up using non constant memory models for some of the libatomic
functions. These all end up as __ATOMIC_SEQ_CST. Just use this
directly. This avoids a new warning for non constant memory
models, which broke the bootstrap with -Werror

Passed bootstrap and test on x86_64-linux.
