tools/memory-model: Define applicable tags on operation in tools/...
Herd7 transforms reads, writes, and read-modify-writes by eliminating
'acquire tags from writes, 'release tags from reads, and 'acquire,
'release, and 'mb tags from failed read-modify-writes. We emulate this
behavior by redefining Acquire, Release, and Mb sets in linux-kernel.bell
to explicitly exclude those combinations.
Herd7 furthermore adds 'noreturn tag to certain reads. Currently herd7
does not allow specifying the 'noreturn tag manually, but such manual
declaration (e.g., through a syntax __atomic_op{noreturn}) would add
invalid 'noreturn tags to writes; in preparation, we already also exclude
this combination.
