PR 35158 g++ does not compile valid C++ for loops with -fopenmp

[Manuel López-Ibáñez]

The following patch correctly diagnoses the use of parenthesized
initializers in a OpenMP for loop, which seems to be not allowed by
the standard.
Instead of a cascade of useless errors, it prints the reason to not
accept the code and what it expects.

Bootstrapped and regression tested on x86_64-pc-linux-gnu wit
--enable-languages=all.

OK for trunk?
