This commit removes async/await/suspend/resume from the language
reference, as that feature does not yet work in the self-hosted
compiler.
We will be regressing this feature temporarily. Users of these language
features should stick with 0.10.x with the `-fstage1` flag until they
are restored.
See tracking issue #6025.
The packed struct example was mistakenly applying endianness where it
shouldn't have been. This wasn't being caught because we don't currently
test the examples on Big-endian systems.
I updated the test to remove the endianness where it didn't apply, and
added a new part of the test to demonstrate when it would apply.
* When a field starts at some bit offset within a byte you need to load
starting from that byte and shift, not starting from the next byte,
so a rounded-down divide is required here, not a rounded-up one.
* Remove paragraph from doc that no longer relates to anything.
Closes#12363
Storing defers this way has the benefits that the defer doesn't get
analyzed multiple times in AstGen, it takes up less space, and it
makes Sema aware of defers allowing for 'unreachable else prong'
error on error sets in generic code.
The disadvantage is that it is a bit more complex and errdefers with
payloads now emit a placeholder instruction (but those are rare).

saying []T is a pointer is confusing because zig docs say there are two types of pointers (*T and [*]T). It is more clear to say that []T is a slice type which contains a [*]T pointer and a length.

This reverts commit 7cbd586ace.
This is causing a fail to build from source:
```
./lib/std/fmt.zig:492:17: error: cannot format optional without a specifier (i.e. {?} or {any})
@compileError("cannot format optional without a specifier (i.e. {?} or {any})");
^
./src/link/MachO/Atom.zig:544:26: note: called from here
log.debug(" RELA({s}) @ {x} => %{d} in object({d})", .{
^
```
I looked at the code to fix it but none of those args are optionals.
The current phrasing is vague; it is unclear whether it is demonstrating an example of the type of permitted behavior, from which the rule set must be extrapolated, or it is stating that this restriction only applies to the relationship between integers and bare structs.
Rename all references of sparcv9 to sparc64, to make Zig align more with
other projects. Also, added new function to convert glibc arch name to Zig
arch name, since it refers to the architecture as sparcv9.
This is based on the suggestion by @kubkon in PR 11847.

stage2: change logic for detecting whether the main package is inside
the std package. Previously it relied on realpath() which is not portable.
This uses resolve() which is how imports already work.
* stage2: fix cleanup bug when creating Module
* flatten lib/std/special/* to lib/*
- this was motivated by making main_pkg_is_inside_std false for
compiler_rt & friends.
* rename "mini libc" to "universal libc"
