Use the `collect_and_partition_mono_items ` query to avoid calling the collector

This function has no side effects, and its result is ignored.

Include the kind of the binding that we're suggesting, and use a
structured suggestion.

It requires an unreachable IP address, but there is no such thing, and
this has caused it to fail for multiple people.

Fixes rust-lang#44698, fixes rust-lang#50065.

Stabilize cfg_target_vendor

This stabilizes the use of `cfg(target_vendor = "...")` and removes the corresponding `cfg_target_vendor` feature. Other unstable cfgs remain behind their existing feature gates.

This functionality was added back in 2015 in rust-lang#28612 to complete the coverage of target tuples (`<arch><sub>-<vendor>-<os>-<env>`). [RFC 131](https://github.com/rust-lang/rfcs/blob/master/text/0131-target-specification.md) governs the target specification, not including `target_vendor` seems to have just been an oversight. `target_os`, `target_family`, and `target_arch` are stable as of 1.0.0. `target_env` was also not mentioned in RFC 131, was added in rust-lang#24777, never behind a feature_gate, and insta-stable at 1.1.0.

The functionality is tested in [test/run-pass/cfg/cfg-target-vendor.rs](https://github.com/rust-lang/rust/blob/master/src/test/run-pass/cfg/cfg-target-vendor.rs).

Closes rust-lang#29718
