The existing implementation of bogo_shim_test does not support tests
that use the -expect-advertised-alpn flag or the -select-alpn flag. This
change allows bogo_shim_test to receive and enforce these flags.
Support for these flags is added in the same change because these flags are set together.

This CL adds support of "library", i.e. c-shared, build mode on
wasip1. When -buildmode=c-shared is set, it builds a Wasm module
that is intended to be used as a library, instead of an executable.
It does not have the _start function. Instead, it has an
_initialize function, which initializes the runtime, but not call
the main function.
This is similar to the c-shared build mode on other platforms. One
difference is that unlike cgo callbacks, where Ms are created on-
demand, on Wasm we have only one M, so we just keep the M (and the
G) for callbacks.

We currently avoid marking shifts of constants as bounded, where

We do this because it causes different rule applications during lowering

Add some new rules which ensure that we get the right final instruction
sequence regardless of the ordering. Then we can remove this special case.

The spec says that an embedded field must be specified
as a type name (or a pointer to a type name). This is
explicit in the prose and the FieldDecl syntax.
However, the prose on promoted methods required a named
type (originally the term used for a "defined type").
Before the introduction of alias types, type names could
only refer to named/defined types, so the prose was ok.
With the introduction of alias types in Go 1.9, we
distinguished between defined types (i.e., types given
a name through a type declaration) and type aliases
(types given an alternative name), and retired the notion
of a named type since any type with a name (alias type
and defined type) could be considered a "named type".
To make things worse, with Go 1.18 we re-introduced the
notion of a named type which now includes predeclared
types, defined types, type parameters (and with that
type aliases denoting named types).
In the process some of the wording on method promotion
didn't get updated correctly. At attempt to fix this
was made with CL 406054, but while that CL's description
correctly explained the intent, the CL changed the prose
from "defined type" to "named type" (which had the new
meaning after Go 1.18), and thus did not fix the issue.
This CL fixes that fix by using the term "type name".
This makes the prose consistent for embedded types and
in turn clarifies that methods of embedded alias types
(defined or not) can be promoted, consistent with the
implementation.
While at it, also document that the type of an embedded
field cannot be a type parameter. This restriction has
been in place since the introduction of type parameters
with Go 1.18 and is enforced by the compiler.

Only honor //go:build language version downgrades if the version
specified is 1.21 or greater. Before 1.21 the version in //go:build
lines didn't have the meaning of setting the file's language version.
This fixes an issue that was appearing in GOPATH builds: Go 1.23 started
providing -lang versions to the compiler in GOPATH mode (among other
places) which it wasn't doing before.
For example, take a go file with a //go:build line specifying go1.10.
If that file used a 1.18 feature, that use would compile fine with a Go
1.22 toolchain. But, before this change, it would produce an error when
compiling with the 1.23 toolchain because it set the language version to
1.20 and disallowed the 1.18 feature. This breaks backwards
compatibility: when the build tag was added, it did not have the meaning
of restricting the language version.

"panic during runtime execution" as we're already in runtime when
crash is called. Instead, just abort, which crashes hard and
terminates the Wasm module execution, and the execution engine
often dumps a stack trace.

CL 603055 added basic support of wasmexport. This CL follows it
and adds stack unwinding handling. If the wasmexport Go function
returns normally, we directly return to the host. If the Go
function unwinds the stack (e.g. goroutine switch, stack growth),
we need to run a PC loop to call functions on the new stack,
similar to wasm_pc_f_loop. One difference is that when the
wasmexport function returns normally, we need to exit the loop and
return to the host.
Now a wasmimport function can call back into the Go via wasmexport.
During the callback the stack could have moved. The wasmimport
code needs to read a new SP after the host function returns,
instead of assuming the SP doesn't change.

This CL adds a compiler directive go:wasmexport, which applies to
a Go function and makes it an exported function of the Wasm module
being built, so it can be called directly from the host. As
proposed in #65199, parameter and result types are limited to
32-bit and 64-bit integers and floats, and there can be at most
one result.
As the Go and Wasm calling conventions are different, for a
wasmexport function we generate a wrapper function does the ABI
conversion at compile time.
Currently this CL only adds basic support. In particular,
- it only supports executable mode, i.e. the Go wasm module calls
into the host via wasmimport, which then calls back to Go via
wasmexport. Library (c-shared) mode is not implemented yet.
- only supports wasip1, not js.
- if the exported function unwinds stacks (goroutine switch, stack
growth, etc.), it probably doesn't work.
TODO: support stack unwinding, c-shared mode, js.

A number of tests of "go vet" needed to be updated, either
to avoid mistakes caught by the analyzer, or to suppress

Also, reflect the change in go test help message.

According to inode(7), atime is changed when more than 0 bytes are read
from the file. So, one possible solution to these flakes is to make the
test files empty, so no one can read more than 0 bytes from them.

The syscall.OpenCurrentProcessToken call in user.Current fails
when called from an impersonated thread, as the process token is
normally in that case.
This change ensures that the current thread is not impersonated
when calling OpenCurrentProcessToken, and then restores the
impersonation state, if any.

Go utilizes copy_file_range(2) for file-to-file copying only on kernel 5.3+,
but even on 5.3+ this system call can still go wrong for some reason (check
out the comment inside poll.CopyFileRange).
Before Linux 2.6.33, out_fd must refer to a socket, but since Linux 2.6.33
it can be any file. Thus, we can employ sendfile(2) for copy between files
when copy_file_range(2) fails to handle the copy, that way we can still
benefit from the zero-copy technique on kernel <5.3 and wherever
copy_file_range(2) is available but broken.

Move some code from when we learn that we take a branch, to when
we learn that a boolean is true or false. It is more consistent
this way (and may lead to a few more cases where we can derive
useful relations).
