96c94c2c83 cmd/compile/internal/types2: slightly relax notion of structural type
If we have all channel types in a constraint, there is no structural type
if they don't all have the same channel direction (and identical element
types, of course). By allowing different channel types for the purposes of
the structural type, as long as there is not a send-only _and_ a receive-
only channel in the type set, we make it possible to find a useful, if
restricted by channel direction, structural type where before there was
none.

So if we have unrestricted and send-only channels, the structural type is
the send-only channel, and vice versa.

For all operations on channels that rely on a structural type, it's always
ok to have an unrestricted channel, so this is not affecting their behavior.
But it makes those operations more flexible in the presence of type parameters
containing mixed channel types.

For constraint type inference, where we currently may not infer a channel
at all, this change allows us to infer a more restricted channel (send- or
receive-only). If the inferred channel type is a valid type argument we win;
if not we haven't lost anything.

Use structuralType for send and receive operations and adjust related
error messages (the error message that change are the ones involving
type parameters, so historic error messages are preserved).

Fixes #45920.

229b909313 cmd/compile: don't do Resolve on OKEY identifiers during import
For generic functions, we can export untransformed OKEY nodes, and the
key identifier is written as an ONONAME. But in this case, we do not
want to call Resolve() on the identifier, since we may resolve to a
global type (as happens in this issue) or other global symbol with the
same name, if it exists. We just want to keep the key identifier as an
Ident node.

To solve this, I added an extra bool when exporting an ONONAME entry,
which indicates if this entry is for a key or for a global (external)
symbol. When the bool is true (this is for a key), we avoid calling
Resolve().

Fixes #49497

Adds a new flag to 'go mod vendor' which overrides the default

4aa0746f6a cmd/go: add workspace pruning mode
[ this is a roll-forward of golang.org/cl/357169 with minor changes
to fix the cmd/go/internal/modload tests: because they don't run the
go command, some initialization isn't run on the test and modroots is
empty in cases it can't be when the full command setup is done. So
directly check for workFilePath != "" instead of calling inWorkspaceMode
which checks that Init is called first, and check that modRoots is non
empty when calling mustGetSingleMainModule.]

This change corrects a bug in the handling of module loading of
workspaces. Namely, there is an assumption by the module pruning code
that if a root module is selected then the packages of that module can
be resolved without loading the whole module graph. This is not true
in workspace mode because two workspace modules can require different
versions of a dependency. Worse, one workspace module can directly
require a depencency that is transitively required by another
workspace module, changing the version of that module loaded in the
fully expanded graph.

To correct this, a new 'workspace' pruning mode is added where the
roots are the workspace modules themselves, satisfying the assumption
made by the module pruning logic.

The rest of this change accounts for the new pruning mode where it's
used and correctly sets the requirements in this pruning mode.

805b4d5636 cmd/dist: wait for exit in bgwait after a fatal error
Currently, when a command scheduled by bgrun fails, bgwait returns to
the caller even in case the fatal error was detected.

In case of a syntax error in one of the standard packages, as an
example, the runInstall function will try to read the generated archive
file, only to fail since the file does not exist.  Since the runInstall
function is called in a goroutine, cmd/dist will continue to report
errors until all background goroutines are done.

Update the bgwait function to wait until program termination in case of
a fatal error, since returning to the caller (with an error, as an
example) will cause cmd/dist to report an additional error during the
next build phase.

233ea216c7 all: update vendored golang.org/x/{arch,sys,term} for Go 1.18 release
The Go 1.18 code freeze has recently started. This is a time to update
all golang.org/x/... module versions that contribute packages to the
std and cmd modules in the standard library to latest master versions.

This CL updates only the lower-level modules arch, sys, term for better
bisection. The next CL will update further ones.

For #36905.

36dbf7f7e6 cmd/go: add //go:embed all:pattern
When //go:embed d matches directory d, it embeds the directory
tree rooted at d, but it excludes files beginning with . and _,
as well as files having problematic names that will not be packaged
into modules (names such as .git and com1).

After long discussions on #42328 and #43854, we decided to keep
the behavior of excluding . and _ files by default, but to allow the pattern
prefix 'all:' to override this default. This CL implements that change.

Note that paths like .git and com1 are still excluded, as they must be,
since they will never be packed into a module.

Fixes #43854.

15a54d627c runtime: add upper half and carry bit with zero
https://golang.org/cl/246763 accidentally changed this from upper + 0 +
carry to upper + old vdsoSP + carry.

The old value of vdsoPC is usually zero, so this typically works.
However, the reentrant case will have a non-zero value, resulting in a
bogus returned time.
