PR c/65083 notes that some functions in <stdatomic.h> are normal functions, not generic functions, and so need to have out-of-line copies that can be called when macro expansion is suppressed (unlike the generic functions where DR#419 makes it undefined if you suppress a macro expansion).This patch adds such out-of-line definitions in libatomic for those six functions, at a new LIBATOMIC_1.2 symbol version, as trivial wrappers to the <stdatomic.h> macros, along with declarations of those functions in <stdatomic.h>. Tests are added that are based on the corresponding tests for the macros, but with parentheses around the function names to force the out-of-line functions to be used. Bootstrapped with no regressions on x86_64-pc-linux-gnu.

OK. Thanks, Jeff
