c5fee935bb cmd/link: force eager binding when using plugins on darwin
When building/using plugins on darwin, we need to use flat
namespace so the same symbol from the main executable and the
plugin can be resolved to the same address. Apparently, when using
flat namespace the dynamic linker can hang at forkExec when
resolving a lazy binding. Work around it by forcing early bindings.

Fixes #38824.

3c495839fe spec: describe constraint parsing ambiguity and work-around more precisely
The new description matches the implementation (CL 370774).

Also, in the section on type constraints, use "defines" instead of
"determines" because the constraint interface defines the type set
which is precisely the set of acceptable type arguments.

55a25aa6ca net: lengthen arbitrary SetDeadline timeout by a few orders of magnitude
The "someTimeout" constant in the net test is “just to test that
net.Conn implementations don't explode when their SetFooDeadline
methods are called”. It was set to 10 seconds, which is short enough
that it could actually matter on some platforms.

Since the point of the constant is just to make sure methods don't
explode, we should set it to be at least a couple of orders of
magnitude longer than the test: then it is guaranteed not to have any
unintended side-effects.

33a1a93a92 cmd/compile/internal/syntax: fix parsing of type parameter lists
The parser cannot distinguish a type parameter list of the form

[P *T ] or
[P (T)]

where T is not a type literal from an array length specification
P*T (product) or P(T) (constant-valued function call) and thus
interprets these forms as the start of array types.

This ambiguity must be resolved explicitly by placing *T inside
an interface, adding a trailing comma, or by leaving parentheses
away where possible.

This CL adjusts the parser such that these forms are
interpreted as (the beginning) of type parameter lists
if the token after P*T or P(T) is a comma, or if T is
a type literal.

This CL also adjusts the printer to print a comma if
necessary to avoid this ambiguity, and adds additional
printer tests.

Fixes #49482

1387b5e91d cmd/compile: only avoid escaping package paths for "go.shape"
We have code that intends to avoid escaping the package path for
built-in packages. But it is hard to determine which packages are
built-in from a general rule, and we really only want to avoid escaping
for the "go.shape" package (since that gives ugly shape type names). So,
fix the code to only avoid escaping the package path specifically for
the "go.shape" package.

b1a53ece68 cmd/go/internal/vcs: prevent Git signatures from breaking commit time parsing
When a user has showSignature=true set in their Git config and the
commit in question has a signature, the git-show command will output
information about that signature. When this happens, the logic that
tries to parsing a timestamp from the git-show output chokes on this
signature information and the build stamping fails. This change prevents
commit signature information from being displayed even if
showSignature=true, preventing this issue.

d01cd8fa1d misc/cgo/testcarchive: log command output more consistently
Also check that executables exist immediately after building them
in parallel tests.

The parallel tests in this package occasionally fail with
"no such file or directory", implying that either the build
command failed to actually write out the binary or something
concurrently deleted it.

This is purely a shot in the dark, but I'm hoping that perhaps
the stderr output from one of these commands will shed some
light on the underlying failure mode.

8108444eaa go/types: record types for union subexpressions
Prior to unions, unary and binary expressions always had a recorded
type. Preserve this by recording a type for all unary and binary
expressions encountered while parsing a union type.

af05064f97 go/types: externalize union type sets
Move calculated type sets for unions into a map, rather than storing
them on the Union type.

Type sets for unions only matter during calculation of interface type
sets, and to a lesser extent inside of Identical. The latter should not
be encountered during type checking, as Identical uses the precomputed
interface type set when comparing interfaces, and unions do not arise
outside of interface types.

Removing the tset field from Union potentially frees up memory, and
eliminates a source of races via calls to NewUnion and Identical. It
also sets the stage for recording Unions for every subexpression of
union terms, which preserves an existing invariant that BinaryExprs and
UnaryExprs should have a recorded type.

d407a8c3c4 testing: retry spurious errors from RemoveAll for temp directories
This works around what appears to be either a kernel bug or a Go
runtime or syscall bug affecting certain Windows versions
(possibly all pre-2016?).

The retry loop is a simplified version of the one used in
cmd/go/internal/robustio. We use the same 2-second arbitrary timeout
as was used in that package, since it seems to be reliable in practice
on the affected builders. (If it proves to be too short, we can
lengthen it, within reason, in a followup CL.)

Since this puts a higher-level workaround in place, we can also revert
the lower-level workaround added to a specific test in CL 345670.

This addresses the specific occurrences of the bug for users of
(*testing.T).TempDir, but does not fix the underlying bug for Go users
outside the "testing" package (which remains open as #25965).

006d4e6278 cmd/compile: fix case where we didn't delay transformAssign in varDecl
We delay all transformations on generic functions, and only do them on
instantiated functions, for several reasons, of which one is that
otherwise the compiler won't understand the relationship between
constrained type parameters. In an instantiation with shape arguments,
the underlying relationship between the type arguments are clear and
don't lead to compiler errors.

This issue is because I missed delaying assignment transformations for
variable declarations. So, we were trying to transform an assignment,
and the compiler doesn't understand the relationship between the T and U
type parameters.

The fix is to delay assignment transformations for variable declarations
of generic functions, just as we do already for normal assignment
statements.

A work-around for this issue would be to just separate the assignment
from the variable declaration in the generic function (for this case of
an assignment involving both of the constrained type parameters).

5b9207ff67 cmd/compile: avoid re-instantiating method that is already imported
We can import an shape-instantiated function/method for inlining
purposes. If we are instantiating the methods of a instantiated type
that we have seen, and it happens to need a shape instantiation that we
have imported, then don't re-create the instantiation, since we will end
up with conflicting/duplicate definitions for the instantiation symbol.
Instead, we can just use the existing imported instantation, and enter
it in the instInfoMap[].
