[PATCH][OBVIOUS] Fix wrong usage of dump_printf_loc (PR tree-optimization/90416).

[Martin Liška]

Hi.

dump_printf_loc is a variadic function and the usafe in tree-vect-stmts.c
is wrongly passing 2nd part of the string format as a first variadic argument.
That's why I saw such a strange crashes.

I'm going to install the patch as soon as it finishes tests.

Thanks,
Martin
