Ryan C. Gordon 73fed37c04 assert: make disabled asserts work with bitfield conditions. 
We don't care _what_ the `sizeof` results are, we just want it to vaporize
the condition's code out of the build. So we check it with a `? 1 : 0`, so it
always boils down to a `sizeof (int)`, no matter what data type the condition
actually is.

This works with bitfields, pointers, anything that can be "truthy." If it
isn't truthy, it would fail when assertions are enabled anyhow.

Fixes #15990.
