The surrogate code points U+D800 to U+DFFF are valid code points but are not Unicode scalar values. This commit makes the error message more accurately reflect what is actually allowed in `\u` escape sequences.
From https://www.unicode.org/versions/Unicode15.0.0/ch03.pdf:
> D71 High-surrogate code point: A Unicode code point in the range U+D800 to U+DBFF.
> D73 Low-surrogate code point: A Unicode code point in the range U+DC00 to U+DFFF.
>
> 3.9 Unicode Encoding Forms
> D76 Unicode scalar value: Any Unicode code point except high-surrogate and low-surrogate code points.

This reverts commit a7de02e052.
This did not implement the accepted proposal, and I did not sign off
on the changes. I would like a chance to review this, please.
* `doc/langref` formatting
* upgrade `.{ .path = "..." }` to `b.path("...")`
* avoid using arguments named `self`
* make `Build.Step.Id` usage more consistent
* add `Build.pathResolve`
* use `pathJoin` and `pathResolve` everywhere
* make sure `Build.LazyPath.getPath2` returns an absolute path
A pointer type already has an alignment, so this information does not
need to be duplicated on the function type. This already has precedence
with addrspace which is already disallowed on function types for this
reason. Also fixes `@TypeOf(&func)` to have the correct addrspace and
alignment.
* make test names contain the fully qualified name
* make test filters match the fully qualified name
* allow multiple test filters, where a test is skipped if it does not
match any of the specified filters
This creates a section in the language reference about doctests, which
is currently referenced by Autodoc in a tooltip when displaying a
doctest.
Some advice relevant to writing doctests is included, based on the
discussion on #16472.
This section documented how a buggy feature worked at one point in time
but it's not a description of what is supposed to happen. What is
supposed to happen is simple enough to not warrant any documentation
about it. When a file is imported, all the test decls are supposed to be
queued for analysis.
Also, refAllDecls() is a hack which should not be celebrated or even
mentioned in the language reference.
