tile: fix bug where fls(0) was not returning 0
commit 9f1d62bed7f015d11b9164078b7fea433b474114 upstream.
This is because __builtin_clz(0) returns 64 for the "undefined" case
of 0, since the builtin just does a right-shift 32 and "clz" instruction.
So, use the alpha approach of casting to u32 and using __builtin_clzll().
