We're guaranteed we won't infinite loop on deadcode-only changes,
because each change converts valid -> invalid, and there are only a
finite number of valid values.
The loops this test is looking for are those generated by rule
applications, so it isn't useful to check for loops when rules aren't
involved.

The Faccessat call checks the user, group, or other permission bits of a
file to see if the calling process can access it. The test to see if the
group permissions should be used was made with the wrong group id, using
the process's group id rather than the file's group id. Fix this to use
the correct group id.
No test since we cannot easily change file permissions when not running
as root and the test is meaningless if running as root.

In #52529, we observed that checking types for duplicate fields and
methods during method collection can result in incorrect early expansion
of the base type. Fix this by delaying the check for duplicate fields.
Notably, we can't delay the check for duplicate methods as we must
preserve the invariant that added method names are unique.
After this change, it may be possible in the presence of errors to have
a type-checked type containing a method name that conflicts with a field
name. With the previous logic conflicting methods would have been
skipped. This is a change in behavior, but only for invalid code.
Preserving the existing behavior would likely require delaying method
collection, which could have more significant consequences.
As a result of this change, the compiler test fixedbugs/issue28268.go
started passing with types2, being previously marked as broken. The fix
was not actually related to the duplicate method error, but rather the
fact that we stopped reporting redundant errors on the calls to x.b()
and x.E(), because they are now (valid!) methods.

When we added VCS stamping in the Go 1.18 release, we defaulted to
-buildvcs=true, on the theory that most folks will actually want VCS
information stamped.
We also made -buildvcs=true error out if a VCS directory is found and
no VCS tool is available, on the theory that a user who builds with
'-buildvcs=true' will be very surprised if the VCS metadata is
silently missing.
However, that causes a problem for CI environments that don't have the
appropriate VCS tool installed. (And we know that's a common situation
because we're in that situation ourselves — see #46693!)
The new '-buildvcs=auto' setting provides a middle ground: it stamps
VCS information by default when the tool is present (and reports
explicit errors if the tool errors out), but omits the metadata
when the tool isn't present at all.

CL 337529 introduced upfront type-checking of constant shift operands,
to avoid converting their type to uint (per the spec). However, it
had an oversight in that the checks intended for non-constant operands
still ran after the explicit checking of constant operands. As a
result, there are at least two bugs:
- When GoVersion is < 1.13, we report spurious errors for untyped
constant shift operands.
- When the operand is an untyped float constant, we still convert to
uint (this was a known bug reported in #47410).
Looking at this now, it seems clear that we can avoid both of these bugs
by simply not running the additional checks in the case of a constant
operand. However, this should be considered with some care, as shifts
are notoriously tricky.
While cherry-picking, the new test file is updated to use the go1_12
package name, following our convention for specifying language version
in the release branch.

Per the spec, "the type sets of all non-interface terms must be
pairwise disjoint (the pairwise intersection of the type sets must
be empty)" in a union.
For the overlap test, the existing implementation casually mixed
syntactic union terms (which may have interface type) with type set
terms (which are normalized/expanded and must not have interface
type). As a consequence, in some cases the overlap test failed.
This change skips terms with interface types in the overlap test.
For this cherry-pick, also rename the files ending in issue51607.go
to issue51607.go2 because the 1.18 branch requires tests containing
generic features to end in .go2.

Users almost never care about versioning for test binaries, because
'go test' runs the test in the source tree and test binaries are only
rarely used outside of 'go test'. So the user already knows exactly
which version the test is built against, because the source code is

For hidden closure built during stenciling to implement a function
instantiation, the function may come from other package, not local
package, which causes the ICE for code that re-export the hidden closure
after inlining.
To fix it, use the closure package for export writer when writing out
the closure itself.
Fixes#51423

When minimizing a value, if the value cannot be minimized (i.e. it is
the final value is the same value as was sent for minimization) return
the initial coverage map, rather than the coverageSnapshot, which is
actually the coverage map for the final minimization step and may not
accurately reflect whether the input actually expands the coverage set
or not.

The removed assertion was never incorrect, as signatures may
be from methods in interfaces, and (some) interfaces set the
receivers of their methods (so we have a position for error
reporting).
This CL changes the issue below from a release blocker to an
issue for Go 1.19.
For #51593.

Pointer types may appear in expressions *P and we don't know if
we have an indirection (P is a pointer value) or a pointer type

a type P must be an ordinary (not a constraint) type in this
special case.
