[PATCH 0/4] atomic: Friendlier assertions, avoidance of __sync

[Richard Henderson]

The current use of _Static_assert, via QEMU_BUILD_BUG_ON, requires
the user have #if conditionals to avoid the statement from appearing
in the preprocessed file at all.  Introduce a new primitive that
allows normal C conditionals and dead-code elimination.

Remove all use of __sync* builtins in favor of __atomic*.
We have required them since 47345e71247, last year, and
should have removed these at that point.  My bad.
