Support for linux/386 was added to Delve in version 1.4.1, but the
version of Delve currently installed on the linux-386-longtest
builder is 1.2.0. That isn't new enough, which causes the test
to fail. Skip it on that builder until it can be made to work.
The only reason it used to pass on the linux-386-longtest builder
before is because that builder was misconfigured to run tests for
linux/amd64. This was resolved in CL 234520.
Also improve internal documentation and the text of skip reasons.

The scheduler assumes two special invariants that apply to tuple
selectors (Select0 and Select1 ops):
1. There is only one tuple selector of each type per generator.
2. Tuple selectors and generators reside in the same block.
Prior to this CL the assumption was that these invariants would
only be broken by the CSE pass. The CSE pass therefore contained
code to move and de-duplicate selectors to fix these invariants.
However it is also possible to write relatively basic optimization
rules that cause these invariants to be broken. For example:
(A (Select0 (B))) -> (Select1 (B))
This rule could result in the newly added selector (Select1) being
in a different block to the tuple generator (see issue #38356). It
could also result in duplicate selectors if this rule matches
multiple times for the same tuple generator (see issue #39472).
The CSE pass will 'fix' these invariants. However it will only do
so when optimizations are enabled (since disabling optimizations
disables the CSE pass).
This CL moves the CSE tuple selector fixup code into its own pass
and makes it mandatory even when optimizations are disabled. This
allows tuple selectors to be treated like normal ops for most of
the compilation pipeline until after the new pass has run, at which
point we need to be careful to maintain the invariant again.

Restore previously sent SCTs and stapled OCSP response during session
resumption for both TLS 1.2 and 1.3. This behavior is somewhat
complicated for TLS 1.2 as SCTs are sent during the server hello,
so they override what is saved in ClientSessionState. It is likely
that if the server is sending a different set of SCTs there is probably
a reason for doing so, such as a log being retired, or SCT validation
requirements changing, so it makes sense to defer to the server in
that case.

Also do not unset it by default in the tests for cmd/go.
GOROOT_FINAL affects the GOROOT value embedded in binaries,
such as 'cmd/cgo'. If its value changes and a build command
is performed that depends on one of those binaries, the binary
would be spuriously rebuilt.
Instead, only unset it in the specific tests that make assumptions
about the GOROOT paths embedded in specific compiled binaries.
That may cause those tests to do a little extra rebuilding when
GOROOT_FINAL is set, but that little bit of extra rebuilding
seems preferable to spuriously-stale binaries.

The page sweeper depends on spans being marked if any object in the
span is marked, but currently only greyobject does this.
gcmarknewobject and wbBufFlush1 also mark objects, but neither set
span marks. As a result, if there are live objects on a span, but
they're all marked via allocation or write barriers, then the span
itself won't be marked and the page reclaimer will free the span,
ultimately leading to memory corruption when the memory for those live
allocations gets reused.
Fix this by making gcmarknewobject and wbBufFlush1 also mark pages.
No test because I have no idea how to reliably (or even unreliably)
trigger this.

This is a followup to CL 96495.
It should be simpler and more robust to achieve .bat files having
CRLF line endings by treating it as a binary file, like all other
files, and checking it in with the desired CRLF line endings.
A test is used to check the entire Go tree, short of directories
starting with "." and named "testdata", for any .bat files that
have anything other than strict CRLF line endings. This will help
catch any accidental modifications to existing .bat files or check
ins of new .bat files.
Importantly, this is compatible with how Gerrit serves .tar.gz files,
making it so that CRLF line endings are preserved.
The Go project is supported on many different environments, some of
which may have limited git implementations available, or none at all.
Relying on fewer git features and special rules makes it easier to
have confidence in the exact content of all files. Additionally, Go
development started in Subversion, moved to Perforce, then Mercurial,
and now uses Git.¹ Reducing its reliance on git-specific features will
help if there will be another transition in the project's future.
There are only 5 .bat files in the entire Go source tree, so a new one
being added is a rare event, and we prefer to do things in Go instead.
We still have the option of improving the experience for developers by
adding a pre-commit converter for .bat files to the git-codereview tool.
