Erase late-bound regions before computing vtable debuginfo name.
Fixes#90019.
The `msvc_enum_fallback()` for computing enum type names needs to access the memory layout of niche enums in order to determine the type name. `compute_debuginfo_vtable_name()` did not properly erase regions before computing type names which made memory layout computation ICE when encountering un-erased regions.

resolve: Use `NameBinding` for local variables and generic parameters
`NameBinding` is a structure used for representing any name introduction (an item, or import, or even a built-in).
Except that local variables and generic parameters weren't represented as `NameBinding`s, for this reason they requires separate paths in name resolution code in several places.
This PR introduces `NameBinding`s for local variables as well and simplifies all the code working with them leaving only the `NameBinding` paths.
The bug was dues to the constant bytes being compared instead of their
values. This meant that negative values were being treated as larger
than some positive values.
Fixes#7829
I think this code is getting L0, not L1 cache size, if I'm reading the Intel manual right. (I might not be.) Either way, the code comment and the printed message should match, whichever way is right. :)

Remove border-bottom from most docblocks.
Headings in the top-doc docblock still get a border-bottom due to a rule
that covers all h2, h3, and h4. Method docblocks are generally h5, and
so don't get a border-bottom anymore.
This fixes a problem where a sub-sub-heading within a method would have
a line that went all the way across the page, creating a division that
made that sub-sub-heading look much more important than it really is.
Fixes#90033

These can't be made const at this time because these use Into::into.
