Rename the legacy feature gating macro
It had a really confusing name by shadowing the previous name, which has
caused issues in the past where people added their new syntax in the
legacy location.
This makes it clear.
Also adds a comment about the return type notation gating, which confused me why it was here at first before `@compiler-errors` told me why.
Fix debug printing of tuple
Self-explanatory. Didn't create a UI test, but I guess I could -- not sure where debug output shows up in rustc_attrs to make a sufficient test, tho.
Add Zba, Zbb, and Zbs as target features for riscv64-linux-android
This pull request adds the Zba, Zbb, and Zbs target features to the `riscv64-linux-android` target specification. These features have been enabled and tested internally in Android infrastructure.
Add Minimal Std implementation for UEFI
# Implemented modules:
1. alloc
2. os_str
3. env
4. math

Tracking Issue: https://github.com/rust-lang/rust/issues/100499
API Change Proposal: https://github.com/rust-lang/libs-team/issues/87
# Additional Information
This was originally part of https://github.com/rust-lang/rust/pull/100316. Since that PR was becoming too unwieldy and cluttered, and with suggestion from `@dvdhrm,` I have extracted a minimal std implementation to this PR.
The example in `src/doc/rustc/src/platform-support/unknown-uefi.md` has been tested for `x86_64-unknown-uefi` and `i686-unknown-uefi` in OVMF. It would be great if someone more familiar with AARCH64 can help with testing for that target.

Raise minimum supported Apple OS versions
This implements the proposal to raise the minimum supported Apple OS versions as laid out in the now-completed MCP (https://github.com/rust-lang/compiler-team/issues/556).
As of this PR, rustc and the stdlib now support these versions as the baseline:
- macOS: 10.12 Sierra
- iOS: 10
- tvOS: 10
- watchOS: 5 (Unchanged)
In addition to everything this breaks indirectly, these changes also erase the `armv7-apple-ios` target (currently tier 3) because the oldest supported iOS device now uses ARMv7s. Not sure what the policy around tier3 target removal is but shimming it is not an option due to the linker refusing.
[Per comment](https://github.com/rust-lang/compiler-team/issues/556#issuecomment-1297175073), this requires a FCP to merge. cc `@wesleywiser.`
More accurate suggestion for `self.` and `Self::`
Detect that we can't suggest `self.` in an associated function without `&self` receiver.
Partially address #115992.
r? ``@compiler-errors``
Check that closure/generator's interior/capture types are sized
check that closure upvars and generator interiors are sized. this check is only necessary when `unsized_fn_params` or `unsized_locals` is enabled, so only check if those are active.

Point at cause of expectation of `break` value when possible
When encountering a type error within the value of a `break` statement, climb the HIR tree to identify if the expectation comes from an assignment or a return type (if the loop is the tail expression of a `fn`).
Fix#115905.
