Go 1.18 development is well underway. This is a time to update all
golang.org/x/... module versions that contribute packages to the std

Add a new test TestImportTypeparamTests that compiles and imports
packages contained in test/typeparam, and compares the resulting package
scope with the scope produced by type-checking directly.
In the process, fix a bug in go/types affecting embedded instances with
more than one type argument. This was uncovered by smoketest.go.
To enable this new test it was easiest to move gcimporter_test.go to an
external test, which required copying the pkgExts variable.

Port the necessary logic to go/internal/gcimporter from
cmd/compile/internal/importer/iimport.go to support type parameters.
This is a partial port of several compiler CLs: at least CL 319930,
CL 322609, CL 323029, CL 338192, CL 340251, and CL 340989. Because these
ports were not interleaved with the corresponding go/types API changes,
it is easier to just take the latest importer logic.
Notably, the equivalent of types2.AsTypeParam is not used. It should be
unnecessary.

Usually, fixalloc is used to allocate small, persistent and reuseable
objects. The size is typically between range [sizeof(mlink), _FixAllocChunk].
It's rare for being out of the range. But if it did happen, we got a
hard-to-discover memory corruption. This commit prevents that situation by limiting object's size.

ORANGE is still not inlineable now. This CL is correct only when the range statement is statically dead, and thus not counted during the inline budget check.
If we support range statements in inlining closures in the future, may require additional processing.

Currently, if a test explicitly specify -G flag, if that flag conflict
with compiler default -G flag, the test will be skipped. That's the
reason CL 346469 haven't fixed the unified IR stuff, but still make the
unified builder passed.
This CL makes run.go always run the test in unified IR mode, regardless
of the explicit -G flag specified.

When type-checking expressions, detection of uninstantiated generic
functions and types was somewhat ad-hoc.
Add an extra parameter "allowGenerics" to rawExpr. If not set, the
result operand cannot be generic.
The only place where rawExpr is called with allowGenerics != false
is from exprOrType, which passes an allowGenerics parameter through.
The only place where exprOrType is called with allowGenerics == true
is when handling index expressions and calls. Make sure that we only
accept generic operands where expected, and check the other branches.
As a result, a recently added varType call (CL 345970) can be removed
again.
This also fixes a bug where an error for a conversion to generic
type was reported after the conversion (i.e., with the converted
value, rather than the generic type). Added a test case for that.
For #48048.

This CL splits the creation of the "init" function responsible for
executing package-scope variable initialization statemens from the
creation of the "inittask" record that tells the runtime how to
sequence all program-wide package initialization.
Longer term, this is desirable because sorting variable initialization
is already handled by types2 (with Info.InitOrder), so we might as
well reuse that.
As a more immediate impetus, for unified IR, I want to defer method
wrapper generation until after inlining (to know which wrappers are
needed). But the staticinit optimization used to decide whether to
emit the inittask calls into reflectdata, which in turn tries to
generate its own method wrappers. So separating the work allows to
create the "init" function early and then emit "inittask" after
inlining is done.
