core/cortex-m: Disable warning in vecttable.c when building with clang
The vecttable logic explicitly routes unused IRQs to IRQ_UNUSED_OFFSET,
and then assigns it to "null" at the very end. The result is something
like:
[8] = __attribute__((used, weak, alias("default_handler")))
irq_55_handler(void);
[8] = __attribute__((used, weak, alias("default_handler")))
irq_56_handler(void);
...
[8] = (void*)0
This is intentional so that it works with a varying values for
CONFIG_IRQ_COUNT.
