Fixes it to correctly treat paths with spaces. This is especially useful given that the default Go install path is under "C:\Program Files".

CL 444277 fixed Time.UnmarshalText and Time.UnmarshalJSON to properly
unmarshal timestamps according to RFC 3339 instead of according
to Go's bespoke time syntax that is a superset of RFC 3339.
However, this change seems to have broken an AWS S3 unit test
that relies on parsing timestamps with single digit hours.
It is unclear whether S3 emits these timestamps in production or
whether this is simply a testing artifact that has been cargo culted
across many code bases. Either way, disable strict parsing for now
and re-enable later with better GODEBUG support.

- Build cmd with CGO_ENABLED=0. Doing so removes the C compiler
toolchain from the reproducibility perimeter and also results in
cmd/go and cmd/pprof binaries that are statically linked,
so that they will run on a wider variety of systems.
In particular the Linux versions will run on Alpine and NixOS
without needing a simulation of libc.so.6.
The potential downside of disabling cgo is that cmd/go and cmd/pprof
use the pure Go network resolver instead of the host resolver on
Unix systems. This means they will not be able to use non-DNS
resolver mechanisms that may be specified in /etc/resolv.conf,
such as mDNS. Neither program seems likely to need non-DNS names
like those, however.
macOS and Windows systems still use the host resolver, which they
access without cgo.
- Build cmd with -trimpath when building a release.
Doing so removes $GOPATH from the file name prefixes stored in the
binary, so that the build directory does not leak into the final artifacts.
- When CC and CXX are empty, do not pick values to hard-code into
the source tree and binaries. Instead, emit code that makes the
right decision at runtime. In addition to reproducibility, this
makes cross-compiled toolchains work better. A macOS toolchain
cross-compiled on Linux will now correctly look for clang,
instead of looking for gcc because it was built on Linux.
- Convert \ to / in file names stored in .a files.
These are converted to / in the final binaries, but the hashes of
the .a files affect the final build ID of the binaries. Without this
change, builds of a Windows toolchain on Windows and non-Windows
machines produce identical binaries except for the input hash part
of the build ID.
- Due to the conversion of \ to / in .a files, convert back when
reading inline bodies on Windows to preserve output file names
in error messages.
Combined, these four changes (along with Go 1.20's removal of
installed pkg/**.a files and conversion of macOS net away from cgo)
make the output of make.bash fully reproducible, even when
cross-compiling: a released macOS toolchain built on Linux or Windows
will contain exactly the same bits as a released macOS toolchain
built on macOS.
The word "released" in the previous sentence is important.
For the build IDs in the binaries to work out the same on
both systems, a VERSION file must exist to provide a consistent
compiler build ID (instead of using a content hash of the binary).

Unified IR added several new IR fields for holding *runtime._type
expressions. To avoid throwing off any frontend semantics
(particularly inlining cost heuristics), they were marked as
`mknode:"-"` so that code wouldn't visit them.
Unfortunately, this has a bad interaction with the static init
inlining optimization, because the latter relies on ir.EditChildren to
substitute all parameters. This potentially includes dictionary
parameters, which can appear within the new RType fields.
This CL adds a new ir.EditChildrenWithHidden function that also edits
these fields, and switches staticinit to use it. Longer term, we
should unhide the RType fields so that ir.EditChildren visits them
normally, but that's scarier so late in the release cycle.
