2020-01-11Rollup merge of #68114 - ecstatic-morse:fix-feature-gating, r=CentrilMazdak Farrokhzad-1/+1
Don't require `allow_internal_unstable` unless `staged_api` is enabled. #63770 changed `qualify_min_const_fn` to require `allow_internal_unstable` for *all* crates that used an unstable feature, regardless of whether `staged_api` was enabled or the `fn` that used that feature was stably const. In practice, this meant that every crate in the ecosystem that wanted to use nightly features added `#![feature(const_fn)]`, which skips `qualify_min_const_fn` entirely. After this PR, crates that do not have `#![feature(staged_api)]` will only need to enable the feature they are interested in. For example, `#![feature(const_if_match)]` will be enough to enable `if` and `match` in constants. Crates with `staged_api` (e.g., `libstd`) require `#[allow_internal_unstable]` to be added to a function if it uses nightly features unless that function is also marked `#[rustc_const_unstable]`. This prevents proliferation of `#[allow_internal_unstable]` into functions that are not callable in a `const` context on stable. r? @oli-obk (author of #63770) cc @Centril
2020-01-10Remove unnecessary `const_fn` feature gatesDylan MacKenzie-1/+1
This flag opts out of the min-const-fn checks entirely, which is usually not what we want. The few cases where the flag is still necessary have been annotated.

This does not update the use sites or delete the now unnecessary SourceMapper trait, to allow git to interpret the file move as a rename rather than a new file.
