`@` pointers used to have special rooting and regions management. With `@`
moving to standalone library, we don't need to keep that special
treatment around. This patch modifies the way `@` pointers are treated by
treating them as if they were `~` pointers
Region checker and borrow checker were modified in this patch.
Closes#11586
[breaking-change]
This pull request:
- Merges the `Round` trait into the `Float` trait, continuing issue #10387.
- Has floating point functions take their parameters by value.
- Cleans up the formatting and organisation in the definition and implementations of the `Float` trait.
More information on the breaking changes can be found in the commit messages.
Now with proper checking of enums and allows unsized fields as the last field in a struct or variant. This PR only checks passing of unsized types and distinguishing them from sized ones. To be safe we also need to control storage.
Closes issues #12969 and #13121, supersedes #13375 (all the discussion there is valid here too).
This currently requires linking against a library like libquadmath (or
libgcc), because compiler-rt barely has any support for this and most
hardware does not yet have 128-bit precision floating point. For this
reason, it's currently hidden behind a feature gate.
When compiler-rt is updated to trunk, some tests can be added for
constant evaluation since there will be support for the comparison
operators.

When a uv_tcp_t is closed in libuv, it will still invoke the pending connect_cb,
and I thought that it would always call it with ECANCELED, but it turns out that
sometimes we'll get a different error code instead. Handle this case by checking
to see if the request's data is NULL and bail out if so (the timeout expired).
