```
std.mem: use indexOfScalarPos when indexOf is called where needle.len == 1

When `std.mem.indexOf` is called with a single-item needle, use `indexOfScalarPos` which is significantly faster than the more general `indexOfPosLinear`.  This can be done without introducing overhead to normal cases (where `needle.len > 1`).
```
