Rather than conditionally assigning ujn, initialise ujn above the
loop to invent the leading 0 for u, then unconditionally load ujn
at the bottom of the loop. This code operates on the basis that
n >= 2, hence j+n-1 is always greater than zero.

Before this change, test binaries didn't have build info populated on them
unless they were tests for package main. Now we generate them for all
test binaries so that they can be inspected like other binaries.
We don't need to add the default GODEBUG in printLinkerConfig because it
will now always be present on the build info, and when build info is
present we use it to generate the hash.

clone(CLONE_PIDFD) was added in Linux 5.2 and pidfd_open was added in
Linux 5.3. Thus our feature check for pidfd_open should be sufficient to
ensure that clone(CLONE_PIDFD) works.
Unfortuantely, some alternative Linux implementations may not follow
this strict ordering. For example, QEMU 7.2 (Dec 2022) added pidfd_open,
but clone(CLONE_PIDFD) was only added in QEMU 8.0 (Apr 2023).
Debian bookworm provides QEMU 7.2 by default.

The ANDN, ORN and XNOR RISC-V Zbb extension instructions are easily
synthesised. Make them always available by adding support to the
riscv64 assembler so that we either emit two instruction sequences,
or a single instruction, when permitted by the GORISCV64 profile.
This means that these instructions can be used unconditionally,
simplifying compiler rewrite rules, codegen tests and manually
written assembly.
Around 180 instructions are removed from the Go binary on riscv64
when built with rva22u64.

Previously we expected the default GODEBUG that's embedded in the binary
to be taken into account for build actionIDs through the build info. The
build info contains the default GODEBUG for a package main, and then
that build info is used to generate the action id. But tests of packages
other than main do not have buildinfo set on them. So the default
GODEBUG isn't taken into account in the action id for those tests.
Explicitly include GODEBUG when generating all link actions' action ids
to make sure it's always present.

asm_riscv64.h will be used to define macros for each riscv64
extension that is not part of the rva20u64 base profile but that the
_riscv64.s assembly files are allowed to use because the user has
specified a more capable profile in the GORISCV64 variable. This will
allow us, for example, to test for the hasZba macro in those assembly
files instead of the GORISCV64_rva22u64 macro before using a Zba
instruction. This is important as it means that in the future when
we add support for new profiles that support Zba, e.g., rva23u64,
we only need to update asm_riscv64.h to indicate rva23u64 supports
Zba. We will not need to update every assembly language file that
already uses Zba instructions.
