optimize Eq implementation for paths

Filesystems generally have a tree-ish structure which means paths are more likely to share a prefix than a suffix. Absolute paths are especially prone to share long prefixes.

quick benchmark consisting of a search through through a vec containing the absolute paths of all (1850) files in `compiler/`:

```
# old
test path::tests::bench_path_cmp                                  ... bench:     227,407 ns/iter (+/- 2,162)

# new
test path::tests::bench_path_cmp                                  ... bench:      64,976 ns/iter (+/- 1,142)
```
