In the past, this exclusion saved 30MB of heavy intrinsics data from ending up in rust-src. However, this filter has been outdated since rust-lang/stdarch#1894, which moved the data to library/stdarch/intrinsics_data. These intrinsics have also shrunk since then, and now sit around 12MB (300KB when compressed).

So this specific change only adds a few KBs:

rust-src compressed unpacked
before 8.01 MB 76.5 MB
after 8.06 MB 76.9 MB

The motivation for this change would be simplifying integration of the stdarch test suite into cg_clif.

For completeness, if we instead fixed the filter to point to the new data location, we'd shrink the dist to:

rust-src compressed unpacked
filtered 7.64 MB 64.7 MB

Hm, those ~12MB we'd get by dropping the data after unpacking would be nice, but I think we can take the current step for now -- seems broadly harmless.

I wonder if the implication there is that intrinsics_data should store compressed copies of the data, rather than keeping the raw contents in the repository? Or at least support using a compressed form (in which case we could compress in bootstrap for example)? Most users would probably be happier with that disk space use (and it's probably a bit faster to write to disk as well).
