This will be relevant once #31605 is merged.
In general, stack traces do *not* contain unique addresses for inlined
frames, but for error return traces, they will after the above PR. This
bool indicates that code printing the trace should not try to resolve
inline frames since they're explicitly encoded into the instruction
addresses.
This is set as state on stack trace rather than passed into the
formatting methods as an argument, as it's not really a formatting
option--whether or not it's correct to resolve inlines is decided at the
time of capture!

std.Thread.Mutex.Recursive remains... for now. it will be replaced with
a special purpose mechanism used only by panic logic.
std.Io.Threaded exposes mutexLock and mutexUnlock for the advanced case
when you need to call them directly.
This commit sketches an idea for how to deal with detection of file
streams as being terminals.
When a File stream is a terminal, writes through the stream should have
their escapes stripped unless the programmer explicitly enables terminal
escapes. Furthermore, the programmer needs a convenient API for
intentionally outputting escapes into the stream. In particular it
should be possible to set colors that are silently discarded when the
stream is not a terminal.
This commit makes `Io.File.Writer` track the terminal mode in the
already-existing `mode` field, making it the appropriate place to
implement escape stripping.
`Io.lockStderrWriter` returns a `*Io.File.Writer` with terminal
detection already done by default. This is a higher-level application
layer stream for writing to stderr.
Meanwhile, `std.debug.lockStderrWriter` also returns a `*Io.File.Writer`
but a lower-level one that is hard-coded to use a static single-threaded
`std.Io.Threaded` instance. This is the same instance that is used for
collecting debug information and iterating the unwind info.
instead, allow the user to set it as a field.
this fixes a bug where leak printing and error printing would run tty
config detection for stderr, and then emit a log, which is not necessary
going to print to stderr.
however, the nice defaults are gone; the user must explicitly assign the
tty_config field during initialization or else the logging will not have
color.

This is a major refactor to `Step.Run` which adds new functionality,
primarily to the execution of Zig tests.
* All tests are run, even if a test crashes. This happens through the
same mechanism as timeouts where the test processes is repeatedly
respawned as needed.
* The build status output is more precise. For each unit test, it
differentiates pass, skip, fail, crash, and timeout. Memory leaks are
reported separately, as they do not indicate a test's "status", but
are rather an additional property (a test with leaks may still pass!).
* The number of memory leaks is tracked and reported, both per-test and
for a whole `Run` step.
* Reporting is made clearer when a step is failed solely due to error
logs (`std.log.err`) where every unit test passed.
added adapter to AnyWriter and GenericWriter to help bridge the gap
between old and new API
make std.testing.expectFmt work at compile-time
std.fmt no longer has a dependency on std.unicode. Formatted printing
was never properly unicode-aware. Now it no longer pretends to be.
Breakage/deprecations:
* std.fs.File.reader -> std.fs.File.deprecatedReader
* std.fs.File.writer -> std.fs.File.deprecatedWriter
* std.io.GenericReader -> std.io.Reader
* std.io.GenericWriter -> std.io.Writer
* std.io.AnyReader -> std.io.Reader
* std.io.AnyWriter -> std.io.Writer
* std.fmt.format -> std.fmt.deprecatedFormat
* std.fmt.fmtSliceEscapeLower -> std.ascii.hexEscape
* std.fmt.fmtSliceEscapeUpper -> std.ascii.hexEscape
* std.fmt.fmtSliceHexLower -> {x}
* std.fmt.fmtSliceHexUpper -> {X}
* std.fmt.fmtIntSizeDec -> {B}
* std.fmt.fmtIntSizeBin -> {Bi}
* std.fmt.fmtDuration -> {D}
* std.fmt.fmtDurationSigned -> {D}
* {} -> {f} when there is a format method
* format method signature
- anytype -> *std.io.Writer
- inferred error set -> error{WriteFailed}
- options -> (deleted)
* std.fmt.Formatted
- now takes context type explicitly
- no fmt string
Functions like isMinGW() and isGnuLibC() have a good reason to exist: They look
at multiple components of the target. But functions like isWasm(), isDarwin(),
isGnu(), etc only exist to save 4-8 characters. I don't think this is a good
enough reason to keep them, especially given that:
* It's not immediately obvious to a reader whether target.isDarwin() means the
same thing as target.os.tag.isDarwin() precisely because isMinGW() and similar
functions *do* look at multiple components.
* It's not clear where we would draw the line. The logical conclusion before
this commit would be to also wrap Arch.isX86(), Os.Tag.isSolarish(),
Abi.isOpenHarmony(), etc... this obviously quickly gets out of hand.
* It's nice to just have a single correct way of doing something.
