If one tries to use promoted fields in a struct literal, the compiler
errors correctly. However, if the embedded fields are of struct pointer
type, the field.Type.Sym.Name expression below panics.
This is because field.Type.Sym is nil in that case. We can simply use
field.Sym.Name in this piece of code though, as it only concerns
embedded fields, in which case what we are after is the field name.
Added a test mirroring fixedbugs/issue23609.go, but with pointer types.
Fixes#26416.

In CLs 122575 and 123177 the cgo tool started explicitly looking up
typedefs. When there are two Go files using import "C", and the first
one has an incomplete typedef and the second one has a complete
version of the same typedef, then we will now record a version of the
first typedef which will not match the recorded version of the second
typedef, producing an "inconsistent definitions" error. Fix this by
silently merging incomplete typedefs with complete ones.

Within the zip file for a given module, disallow names that are invalid
on various operating systems (mostly Windows), and disallow
having two different paths that are case-fold-equivalent.
Disallowing different case-fold-equivalent paths means the
zip file content is safe for case-insensitive file systems.
There is more we could do to relax the rules later, but I think
this should be enough to avoid digging a hole in the early days
of modules that's hard to climb out of later.
In tests on my repo test corpus, the repos now rejected are:
github.com/vjeantet/goldap v0.0.0-20160521203625-ea702ca12a40

The : and ? are reserved on Windows,
and the : is half-reserved (and quite confusing) on macOS.
The ☺ is perhaps an overreach, but I am not convinced
that allowing all of category So is safe; certainly Sk is not.

Over time there may exist two modules with names that differ only in case.
On systems with case-insensitive file systems, we need to make sure those

Module paths, like import paths, are case-sensitive, for better or worse.
But not all file systems distinguish file paths with different cases.
If we are going to use module paths to construct file system paths,
we must apply an encoding that distinguishes case without relying
upon the file system to do it.
This CL defines that encoding, the "safe module path encoding".
Module paths today are ASCII-only with limited punctuation,
so the safe module path encoding is to convert the whole path
to lower case and insert an ! before every formerly upper-case letter:
github.com/Sirupsen/logrus is stored as github.com/!sirupsen/logrus.
Although this CL defines the encoding, it does not change the rest
of the go command to use the encoding. That will be done in
follow-up CLs.

Since Go1.10, go test runs vet on the tests before executing them.
Moreover, the vet tool typechecks the package under analysis with
go/types before running. In Go1.10, a typechecking failure just caused
a warning to be printed. In Go1.11, a typechecking failure will cause
vet to exit with a fatal error (see Issue #21287).
This means that starting with Go1.11, tests that don't typecheck will
fail immediately. This would not normally be an issue, since a test
that doesn't typecheck shouldn't even compile, and it should already
be broken.
Unfortunately, there's a bug in gc that makes it accept programs with
unused variables inside a closure (Issue #3059). This means that a
test with an unused variable inside a closure, that compiled and
passed in Go1.10, will fail in the typechecking step of vet starting
with Go1.11.
Explain this in the 1.11 release notes.

This reverts commit c99300229d.
The original CL skipped the lldb test if it couldn't read compressed
DWARF, but lldb can never read compressed DWARF, so this effectively
disabled this test unconditionally.
The previous commit disabled DWARF compression for this test, so the
test now works on its own merits again. This CL reverts the change to
skip the test so we don't simply mask lldb failures.
Updates #25925.
