3a81adeca2 Call type_of for opaque types later in compilation 
This ensures that various wf checks have already been done before we
typeck item bodies.

Encode less metadata for proc-macro crates 
Currently, we serialize the same crate metadata for proc-macro crates as
we do for normal crates. This is quite wasteful - almost none of this
metadata is ever used, and much of it can't even be deserialized (if it
contains a foreign `CrateNum`).

This PR changes metadata encoding to skip encoding the majority of crate
metadata for proc-macro crates. Most of the `Lazy<[T]>` fields are left
completetly empty, while the non-lazy fields are left as-is.

Additionally, proc-macros now have a def span that does not include
their body. This was done for normal functions in #75465, but was missed
for proc-macros.

As a result of this PR, we should only ever encode local `CrateNum`s
when encoding proc-macro crates. I've added a specialized serialization
impl for `CrateNum` to assert this.

Rollup merge of #77207 - camelid:whence-to-span, r=jyn514 
Rename `whence` to `span`

It's called `span` elsewhere in the compiler and `span` is also less
surprising. `whence` is whimsical, but not super clear :)

Rollup merge of #77161 - est31:swich_len_already_trusted, r=petrochenkov 
Remove TrustedLen requirement from BuilderMethods::switch

The main use case of TrustedLen is allowing APIs to specialize on it,
but no use of it uses that specialization. Instead, only the .len()
function provided by ExactSizeIterator is used, which is already
required to be accurate.

Thus, the TrustedLen requirement on BuilderMethods::switch is redundant.

Rollup merge of #77122 - ecstatic-morse:const-fn-arithmetic, r=RalfJung,oli-obk 
Add `#![feature(const_fn_floating_point_arithmetic)]`

cc #76618

This is a template for splitting up `const_fn` into granular feature gates. I think this will make it easier, both for us and for users, to track stabilization of each individual feature. We don't *have* to do this, however. We could also keep stabilizing things out from under `const_fn`.

Rollup merge of #75454 - ltratt:option_optimisation_guarantees, r=dtolnay 
Explicitly document the size guarantees that Option makes.

Triggered by a discussion on wg-unsafe-code-guidelines about which layouts of `Option<T>` one can guarantee are optimised to a single pointer.
