On AArch64 we have integer modes larger than TImode, and while we can generate
moves for these they're not as efficient.
So instead make sure we limit the maximum we can copy to TImode. This means
copying a 16 byte struct will issue 1 TImode copy, which will be done using a
single STP as we expect but an CImode sized copy won't issue CImode operations.
I am also moving the residual code inside the if since smallest_mode_for_int may
trap if the mode doesn't exist. And the only time we know the mode to exist for
sure is when the condition of the if is true. This also saves repeated calls to
the iterator.

Consider this bogus code (from g++.dg/diagnostic/param-type-mismatch-2.C):
struct s4 { static int member_1 (int one, const char **two, float three); };
int test_4 (int first, const char *second, float third)
{
return s4::member_1 (first, second, third);
}
Before this patch, g++ emits:
demo.cc: In function 'int test_4(int, const char*, float)':
demo.cc:5:44: error: no matching function for call to 's4::member_1(int&, const char*&, float&)'
5 | return s4::member_1 (first, second, third);

Previously the logic that turned "a/b/c/../.." into "a/" failed to
preserve an empty path at the end of the iteration sequence, as required
by the trailing slash. That meant the result didn't meet the class
invariants, and that "a/b/c/d/../../.." would remove four components
instead of the three that "../../.." should remove.
