New search system is based on a Radix Tree. The Radix Tree contains a shallow list of all decl names (ie no paths), plus some suffixes, split by following the official style guide (eg "HashMapUnmanaged" also produces "MapUnmanaged" and "Unmanaged", same with snake_case and camelCase names).
Additionally, the search system uses the decl graph data to recognize hierarchical relationships between decls, allowing you to zero on a target namespace for search. As an example "fs create" will score highe all things related to the creation of files and directories inside of `std.fs`, while still showing (but with lower score) matches from `std.Bulild`.
As another example "fs windows" will prioritize windows-related results in `std.fs`, while "windows fs" will prioritize fs-related results in `std.windows`.

If I could mark a builtin function as cold, I would mark @setCold as cold.
We have run out of `Zir.Inst.Tag`s so I had to move a tag from Zir.Inst.Tag to
Zir.Inst.Extended. This is because a new noreturn builtin will be added and
noreturn builtins cannot be part of Inst.Tag:
```
/// `noreturn` instructions may not go here; they must be part of the main `Tag` enum.
pub const Extended = enum(u16) {
```
Here's another reason I went for @setCold:
```
$ git grep setRuntimeSafety | wc -l
322
$ git grep setCold | wc -l
79
$ git grep setEvalBranchQuota | wc -l
82
```
This also simply removes @setCold from Autodoc and the docs frontend because
as far as I could understand it, builtins represented using Zir extended
instructions are not yet supported because I couldn't find
@setStackAlign or @setFloatMode there, either.
Both original Markdown and CommonMark require at least one space or tab
between the list marker and any following content. Following this allows
starting a line with a negative number or one with a decimal point.
this is a hack meant to restore functionality for the upcoming release,
a proper analysis of the new zir structure is required to make a robust
change.
