Michael Anthony Knyszek a704d39b29 os: hide SetFinalizer from users of Root
Currently Root embeds a root and calls SetFinalizer on &r.root. This
sets the finalizer on the outer root, which is visible to users of
os.Root, and thus they can mutate the finalizer attached to it.

This change modifies Root to not embed its inner root, but rather to
refer to it by pointer. This allows us to set the finalizer on this
independent inner object, preventing users of os.Root from changing the
finalizer. This follows the same pattern as os.File's finalizer.

Fixes #71617.

Daniel McCarney 47d0b0f2bf crypto/internal/fips140test: add TLS-v1.3 ACVP tests
Adds ACVP test coverage for the SP 800-56Crev2 IG 2.4.B TLS v1.3 KDF
based on the NIST spec:

  https://pages.nist.gov/ACVP/draft-hammett-acvp-kdf-tls-v1.3.html

Only SHA2-256 and SHA2-384 are valid hash algorithms for the TLS1.3 KDF
algorithm.

The BoringSSL acvptool "lowers" the more complicated TLS 1.3 KDF ACVP
test cases into simple invocations of our module wrapper's pre-existing
HKDF commands, and the new "HKDFExtract/$HASH" and
"HKDFExpandLabel/$HASH" commands added in this branch.

Updates #69642

Michael Anthony Knyszek ca1cfea371 internal/trace: refactor how experimental batches are exposed
This change modifies how per-generation experimental batches are
exposed. Rather than expose them on the ExperimentalEvent, it exposes it
as part of the Sync event, so it's clear to the caller when the
information becomes relevant and when it should be parsed.

This change also adds a field to each ExperimentalEvent indicating which
experiment the event is a part of.

Because this information needs to appear *before* a generation is
observed, we now ensure there is a sync event both before and after each
generation. This means the final sync event is now a special case;
previously we would only emit a sync event after each generation.

This change is based on feedback from Austin Clements on the
experimental events functionality.

For #62627.

since Windows NT. For example, the || operator runs the RHS operand if
the preceding command failed, determined by checking that the errorlevel
is different from 0. This approach is more robust -it also works with
negative errorlevels- and is less verbose.

Daniel McCarney 273db12cee crypto/internal/fips140test: add DetECDSA ACVP tests
Adds ACVP test coverage for deterministic ECDSA based on the NIST spec:
  https://pages.nist.gov/ACVP/draft-fussell-acvp-ecdsa.html

Notably there is no corresponding acvp_test.config.json update in this
commit because ACVP DetECDSA only specifies sigGen mode.

The ACVP ECDSA sigGen tests are not amenable to testing against
static data because the test vectors don't provide a key pair to use for
the signature, just the message. The module wrapper has to generate its
own keypair and return the public key components with the signature.
DetECDSA produces deterministic signatures only when signing the same
message with the same key.

nolocal is no longer needed after CL 647115. If we remove it, then
we can pass through all arguments to the Go command, which is
useful for running tests with additional flags, like -json or -v.

qmuntal 09fdcdc97d {all,clean,make,race,run}.bat: remove %GOBUILDEXIT% and %GOBUILDFAIL%
%GOBUILDEXIT% is used to avoid closing the terminal window when the
build or the tests fail on a dev machine. It is only set in CI to get
a non-zero exit code in case of failure.

%GOBUILDFAIL% is used to pass the exit code from a child batch file to
the parent batch file. It is set to 1 in the child batch file if the
build or the tests fail.

These two variables add complexity to the batch files and impose some
limitations on how they are implemented. For example, the child files
can't use setlocal, as it would make the parent file unable to read the
%GOBUILDFAIL% variable.

This CL removes these two variables and replaces them with unconditional
calls to "exit /b 1" in case of failure, which is more idiomatic and
composable. The trick is that the "/b" parameter makes the exit only
apply to the current batch file, not the entire shell session (unless
the bat file is the root, in which case the parameter is ignored), so
the parent batch file can continue executing, potentially checking the
errorlevel of the child batch file (which we always set to 1).

Jakub Ciolek cd595be6d6 cmd/compile: prefer an add when shifting left by 1
ADD(Q|L) has generally twice the throughput.

Came up in CL 626998.

Throughput by arch:

Zen 4:

SHLL (R64, 1):   0.5
ADD  (R64, R64): 0.25

Intel Alder Lake:

SHLL (R64, 1):   0.5
ADD  (R64, R64): 0.2

Intel Haswell:

SHLL (R64, 1):   0.5
ADD  (R64, R64): 0.25

Also include a minor opt for:

(x + x) << c -> x << (c + 1)

Before this, the code:

func addShift(x int64) int64 {
    return (x + x) << 1
}

emitted two instructions:

        ADDQ    AX, AX
        SHLQ    $1, AX

but we can do it in a single shift:

        SHLQ    $2, AX

Add a codegen test for clearing the last bit.
