* std.Target.standardDynamicLinkerPath: macOS has a dynamic linker
* no need to override the default dynamic linker in the macos
CrossTarget initialization in the tests
* in getExternalExecutor, when validating the dynamic linker path, take
into account the standard dynamic linker path.
This commit enables stage2 end-to-end tests to run natively on macOS
(where and when applicable). Since QEMU on macOS doesn't support
the same type of architecture emulation as it does on linux (i.e.,
there is no `qemu-x86_64` for instance), this commit ensures that we
specify a path to dynamic linker on macOS (`/usr/lib/dyld`) which
is then checked for existence in `std.CrossTarget.getExternalExecutor()`
function, and if exists, we can run the test natively.

On some distros (e.g. Void Linux) the release field of the tsname
struct may contain an underscore followed by a revision number at the
end. (e.g. 5.8.12_2).
This is convenient for debugging purposes, as well as simplifying the
caching system since executable basenames will not conflict with their
corresponding object files.
stage1 was unable to parse ranges whose starting point was written in
binary/octal as the first dot in '...' was incorrectly interpreted as
decimal point.
stage2 forgot to reset the literal type to IntegerLiteral when it
discovered the dot was not a decimal point.
I've only stumbled across this bug because zig fmt keeps formatting the
ranges without any space around the ...
* 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
