5e3fa0e94f Add rename to std.fs API
- Moves fs.rename functions to fs.renameAbsolute to match other functions outside of fs.Dir
- Adds fs.Dir.rename that takes two paths relative to the given Dir
- Adds fs.rename that takes two separate Dir's that the given paths are relative to (for renaming across directories without having to make the second path relative to a single directory)
- Fixes FileNotFound error return in std.os.windows.MoveFileExW
- Returns error.RenameAcrossMountPoints from renameatW
  + Matches the RenameAcrossMountPoints error return in renameatWasi/renameatZ

27adb82fda std: Respect user-specified alignment when formatting ints
This implementation tries to do the right thing (TM) by treating the
sign as part of the number itself, therefore the alignment parameter
applies to both the sign and the digits.

In other words the format string `{:>4}` with -1 as input will not
output `-  1` but `  -1`.

And let's default to right alignment for everything as that's what users
want, especially when printing numbers. Many implementations use
different defaults for numeric vs non-numeric types, let's strive for a
consistent behaviour here.

b340bbfc1d std: add io_uring library
This brings io_uring helper methods to Zig for kernels >= 5.4.

We follow liburing's design decisions so that anyone who is comfortable with
liburing (https://unixism.net/loti/ref-liburing/index.html) will feel at home.

Thanks to @daurnimator for the first draft.

Before merging, do this for every item in the file:
 * solve the issue, or
 * convert the task to a github issue and update the comment
   to link to the issue (and remove "TODO" text from the comment).
Then delete the file.

778bb4bc9c move std.cache_hash from std to stage2
The API is pretty specific to the implementationt details of the
self-hosted compiler. I don't want to have to independently support
and maintain this as part of the standard library, and be obligated
to not make breaking changes to it with changes to the implementation of
stage2.

2a8fc1a18e stage2: caching system integration & Module/Compilation splitting
* update to the new cache hash API
 * std.Target defaultVersionRange moves to std.Target.Os.Tag
 * std.Target.Os gains getVersionRange which returns a tagged union
 * start the process of splitting Module into Compilation and "zig
   module".
   - The parts of Module having to do with only compiling zig code are
     extracted into ZigModule.zig.
   - Next step is to rename Module to Compilation.
   - After that rename ZigModule back to Module.
 * implement proper cache hash usage when compiling C objects, and
   properly manage the file lock of the build artifacts.
 * make versions optional to match recent changes to master branch.
 * proper cache hash integration for compiling zig code
 * proper cache hash integration for linking even when not compiling zig
   code.
 * ELF LLD linking integrates with the caching system. A comment from
   the source code:

   Here we want to determine whether we can save time by not invoking LLD when the
   output is unchanged. None of the linker options or the object files that are being
   linked are in the hash that namespaces the directory we are outputting to. Therefore,
   we must hash those now, and the resulting digest will form the "id" of the linking
   job we are about to perform.
   After a successful link, we store the id in the metadata of a symlink named "id.txt" in
   the artifact directory. So, now, we check if this symlink exists, and if it matches
   our digest. If so, we can skip linking. Otherwise, we proceed with invoking LLD.

 * implement disable_c_depfile option
 * add tracy to a few more functions

1baa56a25f std.cache_hash: break up the API and improve implementation
into smaller exposed components and expose all of them. This makes it
more flexible.

`*const Cache` is now passed in with an open manifest dir handle which
the caller is responsible for managing.

Expose some of the base64 stuff.

Extract the hash helper functions into `HashHelper` and add some more
methods such as addOptional and addListOfFiles.

Add `CacheHash.toOwnedLock` so that you can deinitialize everything
except the open file handle which represents the file system lock on the
build artifacts.

Use ArrayListUnmanaged, saving space per allocated CacheHash.

Avoid 1 memory allocation in hit() with a static buffer.

hit() returns a bool; caller code is responsible for calling final() in
either case. This is a simpler and easier to use API.

writeManifest() is no longer called from deinit() with errors ignored.

61e9e82bdc std: Make the CRC32 calculation slightly faster
Speed up a little the slicing-by-8 code path by replacing the
(load+shift+xor)*4 sequence with a single u32 load plus a xor.

Before:

```
iterative:  1018 MiB/s [000000006c3b110d]
small keys:  1075 MiB/s [0035bf3dcac00000]

After:

```
iterative:  1114 MiB/s [000000006c3b110d]
small keys:  1324 MiB/s [0035bf3dcac00000]
