Add assembly test to make sure that inlining works as expected when closures inherit target features
Closes https://github.com/rust-lang/rust/issues/108338 (the added test proves that it is working correctly)
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.

Migrate GUI colors test to original CSS color format
Follow-up of https://github.com/rust-lang/rust/pull/111459.
And with this one I'm finally done with this migration.
r? ``@notriddle``
More accurate suggestion for `self.` and `Self::`
Detect that we can't suggest `self.` in an associated function without `&self` receiver.
Partially address #115992.

implement Literal::byte_character
without this, the only way to create a `LitKind::Byte` is by
doing `"b'a'".parse::<Literal>()`, this solves that by enabling
`Literal::byte_character(b'a')`

Enable -Zdrop-tracking-mir by default
This PR enables the `drop-tracking-mir` flag by default. This flag was initially implemented in https://github.com/rust-lang/rust/pull/101692.
This flag computes auto-traits on generators based on their analysis MIR, instead of trying to compute on the HIR body. This removes the need for HIR-based drop-tracking, as we can now reuse the same code to compute generator witness types and to compute generator interior fields.
Add codegen test to guard against VecDeque optimization regression
Very small PR that adds a codegen test to guard against regression for the `VecDeque` optimization addressed in #80836. Ensures that Rustc optimizes away the panic when unwrapping the result of `.get(0)` because of the `!is_empty()` condition.
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.
