Before this commit, the logic would fail with a "LTO not available"
error if the user set `-fno-lto` which doesn't make sense. This commit
corrects the logic to understand when the user is explicitly requesting
to turn LTO off.
This script is sometimes timing out, so let's test fewer things to save
time. The x86_64-windows-release script does include test coverage for
release builds of the standard library, behavior tests, etc.
Introduce introspect.EnvVar which tracks all the environment variables
that are observed by the compiler, so that we can print them with `zig
env`.
The `zig env` command now prints both the resolved values as well as all
the possibly observed environment variables.
The current json output is not very convenient to use from the shell or
a Zig program.
An example using the shell: `zig env | jq -r .lib_dir`.
Remove the json output, and instead use the POSIX shell syntax:
name="value"
Additionally, when args is not empty, assume each argument is the
environment variable name and print the associated value.
Unrecognized environment variables are ignored.
The new output format has been copied from `go env`, with the difference
that `go env` uses OS specific syntax for windows and plan9.
Define the environment variables in a single place, in order to avoid
possible bugs.
XXH3 is the faster alternative to XXH64 which utilizes SIMD
when hashing large chunks of memory and similar mixing to
WyHash (64x64 -> 128 mul) for smaller inputs.

This argument causes zig to print verbose hashing information to stdout,
which can be used to diff two different fetches and find out why the
hashes do not equal each other.
The build was previously failing with `error: unknown command: -print-file-name=libstdc++.a`
because the command invocation was
`zig -print-file-name=libstdc++.a`
instead of
`zig c++ -print-file-name=libstdc++.a`
note: .cxx_compiler_arg1 = "" instead of undefined to avoid breaking existing setups without requiring to run cmake again.
