Hi
This patch adds the no variant to -mstrict-align and the corresponding
function attribute. To enable the function attribute, I have modified
aarch64_can_inline_p () to allow checks even when the callee function
has no attribute. The need for this is shown by the new test
target_attr_18.c.
Testing: Bootstrapped, regtested and added new tests that are copies
of earlier tests checking -mstrict-align with opposite scan directives.
Is this ok for trunk?
