They now all accept yes/no/y/n/on/off values. (Previously only some of
them did.)
This commit also makes `parse_bool` and `parse_opt_bool` more concise
and readable, and adds some helpful comments to some functions.
Maintain chain of derived obligations
When evaluating the derived obligations from super traits, maintain a
reference to the original obligation in order to give more actionable
context in the output.
Continuation (and built on) #69745, subset of #69709.

Minor improvements to -Zprofile
- `-Zprofile` is broken with codegen units because GCOV assumes that each source file corresponds to one object file. This PR makes `-Zprofile` automatically set codegen units to 1 and gives an error if `-Ccodegen-units=X` is specified on the command line (with `X != 1`).
- The `profiler_builtins` crate is not suitable for `no_std` applications since it contains C code that depends on libc. In such cases a custom implementation of the LLVM gcov API (`llvm_gcov_init`, `llvm_gcda_*`) is needed. This PR adds `-Zno-profiler-runtime` flag which inhibits automatic injection of the `profiler_builtins` crate.

Should be save to rollup since we are in no-toolstate-break week (I also didn't see any breakage when testing the clippy with 28742a114)

big-O notation: parenthesis for function calls, explicit multiplication
I saw `O(n m log n)` in the docs and found that really hard to parse. In particular, I don't think we should use blank space as syntax for *both* multiplication and function calls, that is just confusing.
This PR makes both multiplication and function calls explicit using Rust-like syntax. If you prefer, I can also leave one of them implicit, but I believe explicit is better here.
While I was at it I also added backticks consistently.
Use `call` instead of `invoke` for functions that cannot unwind
The `FnAbi` now knows if the function is allowed to unwind. If a
function isn't allowed to unwind, we can use a `call` instead of an
`invoke`.
This resolves an issue when calling LLVM intrinsics which cannot unwind
LLVM will generate an error if you attempt to invoke them so we need to
ignore cleanup blocks in codegen and generate a call instead.
Fixes#69911

This adds a hint on `mem::replace`, "if you don't need the old value,
you can just assign the new value directly". This is in similar spirit
to the `must_use` on `ManuallyDrop::take`.
