Code examples sometimes mistakenly use curvy quotes,
leading to hard-to-spot invalid token errors.
This change makes the error message explicit.
(An alternative change would be to accept them in place
of "abc" and emit an error, but the extra check would
likely add an unacceptable dynamic cost to string scanning.)

In CL 522879, I moved the logic for setting Addrtaken from typecheck's
markAddrOf and ComputeAddrtaken directly into ir.NewAddrExpr. However,
I took the logic from markAddrOf, and failed to notice that
ComputeAddrtaken also set Addrtaken on the canonical ONAME.
The result is that if the only address-of expressions were within a
function literal, the canonical variable never got marked Addrtaken.
In turn, this could cause the consistency check in ir.Reassigned to
fail. (Yay for consistency checks turning mistakes into ICEs, rather
than miscompilation.)

When passing pointers of Go objects from Go to C, the cgo command generate _Cgo_use(pN) for the unsafe.Pointer type arguments, so that the Go compiler will escape these object to heap.
Since the C function may callback to Go, then the Go stack might grow/shrink, that means the pointers that the C function have will be invalid.
After adding the #cgo noescape annotation for a C function, the cgo command won't generate _Cgo_use(pN), and the Go compiler won't force the object escape to heap.
After adding the #cgo nocallback annotation for a C function, which means the C function won't callback to Go, if it do callback to Go, the Go process will crash.

now that this is handled by types2.
And for the same reason, we can stop changing base.Flag.Lang. This was
previously a workaround so that the unified frontend could generate
arbitrary IR without upsetting typecheck, at a time when typecheck was
itself a real frontend. Now it's just a glorified desugaring pass.

There are no changes to what is being tested.
No test cases were removed or added.
Changes made:
* Use a local implementation of test case position marking. See #52751.
* Use consistent names for all test tables and variables.
* Generally speaking, follow modern Go style guide for tests.
* Move global tables local to the test function if possible.
* Make every table entry run in a distinct testing.T.Run.
The purpose of this change is to make it easier to perform
v1-to-v2 development where we want v2 to support close to
bug-for-bug compatibility when running in v1 mode.
Annotating each test case with the location of the test data
makes it easier to jump directly to the test data itself
and understand why this particular case is failing.
Having every test case run in its own t.Run makes it easier
to isolate a particular failing test and work on fixing the code
until that test case starts to pass again.
Unfortunately, many tests are annotated with an empty name.
An empty name is better than nothing, since the testing framework
auto assigns a numeric ID for duplicate names.
It is not worth the trouble to give descriptive names to each
of the thousands of test cases.

This test expects a *Request to be garbage collected
within five seconds. Some slow builders take longer.
Drop the arbitrary timeout.

Also gofmt a test file to make sure the parser works.

The generated constants were already removed by CL 497076, so the cgo
constants used to generate them are no longer needed as well.

TestUnshareMountNameSpaceChroot attempts to build a statically-linked
binary to run in a chroot, and sets CGO_ENABLED=0 in order to do so.
Rather than trying to figure out some other way to coax the linker
into building a static binary, let's just skip the test on Linux
platforms that require external linking (namely android/arm).
This should fix the build failure reported in
https://build.golang.org/log/1ea245a9c2e916c81043db177be76778bab00058.
While we're here, let's also fix the failure logging to make the text
readable!
Updates #46330.

This test passes "-linkmode=external" to 'go run' to link the binary
using the system C linker.
CGO_ENABLED=0 explicitly tells cmd/go not to use the C toolchain,
so the test should not be run in that configuration.

We've added Unparen to go/ast, so add syntax.Unparen to be
consistent (and because it's similarly useful).
Also, types2 and noder both have similar functions for unpacking
ListExprs, so might as well add a common implementation in package
syntax too.
Finally, addressing the TODO: UnpackListExpr is small enough to be
inlined (when default optimizations are enabled), and for typical uses
of UnpackListExpr (e.g., "range UnpackListExpr(x)") the single-element
slice result is stack allocated in the caller. This CL adds a test
using testing.AllocsPerRun to ensure this remains so in the future.

According to RFC 8259, there are exactly 5 control characters
that have a shorter escape sequence than the generic \uXXXX format.
Over the years, we added ad-hoc support for the short sequences:
* https://go.dev/cl/4678046 supports \r and \n
* https://go.dev/cl/162340043 supports \t
This CL completes the set by supporting \b and \f.
This may change the encoding of strings in relatively rare cases,
but is a permissible change since the Go 1 compatibility document does
not guarantee that "json" produces byte-for-byte identical outputs.
In fact, we have made even more observable output changes in the past
such as with https://go.dev/cl/30371 which changes the representation
of many JSON numbers.
This change is to prepare the path forward for a potential
v2 "json" package, which has more consistent encoding of JSON strings.

On Unix platforms, testenv.Command sends SIGQUIT to stuck commands
before the test times out. For subprocesses that are written in Go,
that causes the runtime to dump running goroutines, and in other
languages it triggers similar behavior (such as a core dump).
If the subprocess is stuck due to a bug (such as #57999), that may
help to diagnose it.
For #57999.
