This reverts r359984 (which reverted r359962). The bug in clang-tidy's
test suite exposed by the original commit was fixed in r360009.

__builtin_constant_p.
If the operand of __builtin_constant_p is not constant and has

before the value computation of the result. In C, this is implied by there being

side-effects being sequenced before the expressions and statements in the
function body.

side-effect is not sequenced before its value computation. Also fix a
mishandling of ?: expressions where the condition is constant that was
exposed by the tests for this.
