The Node type has shortcuts to access bool and int Values:
func (n *Node) Int64() int64
for n.Val().U.(*Mpint).Int64()
func (n *Node) Bool() bool
for n.Val().U.(bool)
I was convinced we didn't have one for string literal nodes, until I
noticed that we do, it's just called strlit, it's not a method, and
it's later in the file:
func strlit(n *Node) string
This change, for consistency:
- Renames strlit to StringVal and makes it a *Node method
- Renames Bool and Int64 to BoolVal and Int64Val
- Moves StringVal near the other two

Setting inittrace=1 causes the runtime to emit a single line to standard error for
each package with init work, summarizing the execution time and memory allocation.
The emitted debug information for init functions can be used to find bottlenecks
or regressions in Go startup performance.
Packages with no init function work (user defined or compiler generated) are omitted.
Tracing plugin inits is not supported as they can execute concurrently. This would
make the implementation of tracing more complex while adding support for a very rare
use case. Plugin inits can be traced separately by testing a main package importing
the plugins package imports explicitly.
$ GODEBUG=inittrace=1 go test
init internal/bytealg @0.008 ms, 0 ms clock, 0 bytes, 0 allocs

"aliased" is the function responsible for detecting whether we can
turn "a, b = x, y" into just "a = x; b = y", or we need to pre-compute
y and save it in a temporary variable because it might depend on a.
It currently has two issues:
1. It suboptimally treats assignments to blank as writes to heap
memory. Users generally won't write "_, b = x, y" directly, but it
comes up a lot in generated code within the compiler.
This CL changes it to ignore blank assignments.
2. When deciding whether the assigned variable might be referenced by
pointers, it mistakenly checks Class() and Name.Addrtaken() on "n"
(the *value* expression being assigned) rather than "a" (the
destination expression).
It doesn't appear to result in correctness issues (i.e.,
incorrectly reporting no aliasing when there is potential aliasing),
due to all the (overly conservative) rewrite passes before code
reaches here. But it generates unnecessary code and could have
correctness issues if we improve those other passes to be more
aggressive.
This CL fixes the misuse of "n" for "a" by renaming the variables
to "r" and "l", respectively, to make their meaning clearer.
Improving these two cases shaves 4.6kB of text from cmd/go, and 93kB
from k8s.io/kubernetes/cmd/kubelet:
text data bss dec hex filename
9732136 290072 231552 10253760 9c75c0 go.before
9727542 290072 231552 10249166 9c63ce go.after
97977637 1007051 301344 99286032 5eafc10 kubelet.before
97884549 1007051 301344 99192944 5e99070 kubelet.after
While here, this CL also collapses "memwrite" and "varwrite" into a
single variable. Logically, they're detecting the same thing: are we
assigning to a memory location that a pointer might alias. There's no
need for two variables.

We generally don't care about errors in resolving a repo if the result

avoid some expense in initializing the repo if all of the methods we
plan to call on it hit in the cache — especially when using
GOPROXY=direct.
This also incidentally fixes a possible (but rare) bug in Download:
we had forgotten to reset the downloaded file in case the Zip method

- For "if" statements without a condition, provide a BadExpr rather than nil
(clients expect IfStmt.Cond != nil since the parser is taking care of
reporting a missing condition).
- For 3-index slice expressions, also provide BadExpr where an index is
required but missing.
- Declare a parser-local error method to hide the embedded error method
so we don't use it by mistake.
Accidentally found while adjusting prototype parser to work for generics.

go test runs a limited number of vet checks by default.
In the standard library, we run more, both to get additional checking
for the standard library and to get experience with whether to enable
any others by default.
One that experience has shown us should not be enabled by default
is go vet -unreachable. When you are testing, it is common to want to
put an early return or a panic into code to bypass a section of code.
That often causes unreachable code. It's incredibly frustrating if the
result is an "unreachable code" error that keeps your test from completing.

Currently on darwin, when a symbol needs to be exported, we
export it both statically and dynamically. The dynamic export is
unnecessary for some symbols. Only export the necessary ones.
For special runtime C symbols (e.g. crosscall2), they used to be
exported dynamically, and we had a special case for pclntab to
not include those symbols (otherwise, when the dynamic linker
dedup them, the pclntab entries end up pointing out of the
module's address space). This CL changes it to not export those
symbols, and remove the special case.

On a loaded system, sometimes connections don't work out.
Ignore those in TestTransportPersistConnLeak to avoid flakes.

Add note about using per-use seeds.
Delete "collision-resistant but" in:
> The hash functions are collision-resistant but not cryptographically secure.
"Collision-resistant" has a precise cryptographic meaning that is
incompatible with "not cryptographically secure".
All that is really meant by it here here is "it's a good hash function",
which should be established already.
Also delete:
> The hash value of a given byte sequence is consistent within a
> single process, but will be different in different processes.
This was added for its final clause in response to #37040,
but "The hash value of a given byte sequence" is by design not a
concept in this package. Only "... of a given seed and byte sequence".
And seeds cannot be shared between processes, so again by design
you can't even set up the appropriate first half of the sentence
to say the second half.

This allows multiline constructs like:
{{"hello" |
printf}}
Now that unclosed actions can span multiple lines,
track and report the start of the action when reporting errors.
Also clean up a few "unexpected <error message>" to be just "<error message>".
Fixes#29770.
