This is a port of CL 346471 to go/types. Additionally, CheckExpr was
updated for the new API to explicitly allow generic expressions.
The error messages in issue39634.go2 are different because go/parser
produces an IndexExpr with BadExpr index value, for backward
compatibility.

Fix a hang that occurs when making a request and all of the following apply:
* The request method is one of GET, HEAD, DELETE, OPTIONS, PROPFIND, or SEARCH.
* The Request.Body is non-nil.
* The content length is not set, or is set to -1.
* Transfer-Encoding: chunked is not set.
* The request body does not respond to a read within 200ms.
In this case, we give up on probing for a zero-length body and send the
request while the probe completes in the background. Fix a bug in the
io.Reader wrapping the in-flight probe: It should return io.EOF after
the probe completes, but does not.
Fixes#47568.

In the process, fix a bug in go/types affecting embedded instances with

To enable this new test it was easiest to move gcimporter_test.go to an

Port the necessary logic to go/internal/gcimporter from

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.

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.

In -G=3 mode, irgen use its own generated IR, which is mis-handling of
bodyless function and declared function with //go:noescape pragma.
Fix this by adopting the same logic in noder.funcDecl, which minor
change in linkname detection.

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.

Improve the code which fixes up conditional branches which exceed the

Rather than jumping and branching to a label (the offset for which changes
when instructions are added or removed), use PC-relative offsets. This
reduces unnecessary churn in the instruction encodings.

CL 309831 fixed importing of method expressions, by re-using the same

embedded field.
To fix this, we need to calculate all methods of the receiver base type
