Simplify implied_target_features.
...
Currently its argument is an iterator, but in practice it's always a
singleton.

mark some target features as 'forbidden' so they cannot be (un)set

For now, this is just a warning, but should become a hard error in the future

codegen_ssa: consolidate tied feature checking
...
`rustc_codegen_llvm` and `rustc_codegen_gcc` duplicated logic for
checking if tied target features were partially enabled. This commit
consolidates these checks into `rustc_codegen_ssa` in the
`codegen_fn_attrs` query, which also is run pre-monomorphisation for
each function, which ensures that this check is run for unused functions,
as would be expected.

Reformat use declarations.

The previous commit updated `rustfmt.toml` appropriately. This commit is
the outcome of running `x fmt --all` with the new formatting options.

access.
