The old test "timeout_link_chain1" was ported from liburing test_timeout_link_chain1
509873c445/test/link-timeout.c (L539-L628)
However it turns out that both fails with EBADF (-9) on Linux kernel 5.4.
The this new test skips properly on Linux kernel 5.4
and passes on Linux kernel 5.11.

The end-game for inline assembly is that the syntax is more integrated
with zig, and it will not allow string concatenation for the assembler
code, for the same reasons that Zig does not have a preprocessor.
However, inline assembly in zig right now is lacking for a variety of
use cases (take a look at the open issues having to do with inline
assembly for example), and being able to use comptime expressions to
concatenate text is a workaround that real-world users are exploiting to
get by in the short term.
This commit keeps "assembly code must use string literal syntax" as a
compile error when using stage2, but allows it through when using
stage1.
I expect to revert this commit after making enough improvements to
inline assembly that our real world users' needs are satisfied.
Previously there was only `--single-threaded`.
This flag now matches other boolean flags, instead of only being able to
opt in to single-threaded builds, you can now force multi-threaded
builds. Currently this only has the possibility to emit an error
message, but it is a better user experience to understand why one cannot
choose to enable threads in some cases.
This is breaking change to the CLI.

The INVAL error was marked unreachable which prevents handling
of the error at a higher level.
It seems like it should map to BadPathError based on the man page for
rmdir (and an incomplete understanding of DeleteDirError), which says:
```
EINVAL pathname has . as last component.
```
This mostly reverts commit 692c254336da71cbe21aaf9fbc21240fd1269b95.
The test "for loop over pointers to struct, getting field from struct
pointer" is still failing on the CI so that one is not moved over.

This also modifies tools/update-linux-headers.zig to remove these same
files for next time to prevent a regression.

I don't think we can guarantee that especially for system dyld
dylibs which can be loaded at any address (perhaps even some
OS preferential low memory address).
Incidentally, this fixes stack trace tests on x86_64 macOS 12.
In order to be linker-independent, when parsing debug info in each
linked OSO, we also create a quick lookup table for symbols defined
within the OSO. We then use this lookup to map symbol from the EXE
to its defined address within the original OSO which we can then
use to extract its associated DWARF info (if any).
If a symbol is undefined after we tried resolving it in static and
dynamic libraries, and it is annotated with N_DESC_DISCARDED flag,
we simply ignore it rather than flagging an undefined symbol error.
This reverts commit 0a9b4d092f58595888f9e4be8ef683b2ed8a0da1.
Hm, these are all passing for me locally. I'll have to do some
troubleshooting to figure out which one(s) are failing on the CI.
* Add missing Linux headers. Closes#9837
* Update existing headers to latest Linux.
* Consolidate headers that are the same for multiple Zig target CPU
architectures. For example, Linux has only an x86 directory for both
x86_64 and x86 CPU architectures. Now Zig only ships an x86 directory
for Linux headers, and will emit the proper corresponding -isystem
flags.
* tools/update-linux-headers.zig is now available for upgrading to
newer Linux headers, and the update process is now documented on the
wiki.

Add additional search paths pointing at homebrew prefixes as Apple
doesn't ship a static libncurses for linking - only a stub for dynamic
linking `libncurses.tbd`.
