Josh Triplett 36662dfc83 Fix wrapped valid-range handling in ty_find_init_error ...

Rust's niche handling allows for wrapping valid ranges with end < start;
for instance, a valid range with start=43 and end=41 means a niche of
42. Most places in the compiler handle this correctly, but
ty_find_init_error assumed that `lo > 0` means the type cannot contain a
zero.

Fix it to handle wrapping ranges.

Add a test to cover this case.
