cb50d78a - [C] static_assert in a for loop is not an extension (#151955)

[C] static_assert in a for loop is not an extension (#151955) The original wording can be squinted at to pretend this was always allowed. GCC squints at it that way, so we're doing the same and no longer issuing an extension diagnostic for use of static_assert in the condition-1 of a for loop in C. Fixes #149633
