std.debug.SelfInfo: concrete error sets
...
The downside of this commit is that more precise errors are no longer
propagated up. However, these errors were pretty useless in isolation
due to them having no context; and regardless, we intentionally swallow
most of them in `std.debug` anyway. Therefore, this is better in
practice, because it allows `std.debug` to give slightly more useful
warnings when handling errors. This commit does that for unwind errors,
for instance, which differentiate between the unwind info being corrupt
vs missing vs inaccessible vs unsupported.
A better solution would be to also include more detailed information via
the diagnostics pattern, but this commit is an incremental improvement.

fix aarch64-macos DWARF unwinding
...
turns out this isn't technically specific to that target at all; other
targets just don't emit mid-function 'ret' instructions as much so
certain CFI instruction patterns were only seen on aarch64.
thanks to jacob for finding the bug <3

lib/std/c: sync "struct stat" for DragonFly
...
* Add missing functions like ISDIR() or ISREG(). This is required to
build the zig compiler
* Use octal notation for the S_ constants. This is how it is done for
".freebsd" and it is also the notation used by DragonFly in
"sys/stat.h"
* Reorder S_ constants in the same order as ".freebsd" does. Again, this
follows the ordering within "sys/stat.h"
