The zero value of token.Pos is special: it determines IsValid(), which
has semantic significance in many places.
offsetPositions, which adjusts positions after AST mangling, was
adjusting all positions -- including invalid positions. As a result it
was making invalid positions valid, leaving a nonsensical AST.
Fix it to skip invalid positions.

LSP clients tells gopls which token types it supports using
SemanticTokensClientCapabilites, and when gopls ran into an unsupported
token type it still did send that token with the first supported type
(i.e. encoded token type 0).
This change makes gopls omit tokens where the token type isn't one of
the client supported ones.

Add a new package internal/typeparams/genericfeatures, factoring out the
check for usage of generics from the usesgenerics checker. For tests
operating on the standard library, this allows us to explicitly detect
usage of generics, rather than relying on a hard-coded list.
To make this work, I switched the go/ssa standard library test to use
go/packages rather than go/loader. This resulted in finding 457 packages
versus 676 (likely due to tests), but my assumption is that this is
still enough coverage.

Semantic tokens will now return typeParameters if the client will accept
them. If the user is not using go1.18, then generic code will not type
check and gopls will not recogize type parameters. If gopls has not
been compiled with go1.18 only some uses of type parameters will be
recognized. In any case the code uses internal/typeparams
to see through IndexListExprs.
There is a global parameter semDebug which should be false in
checked-in code. I use it to see how semantic token decisions are
made; it is for debugging. But there are a lot of small code changes
to restrict logging to a few places.
There is also an unexercised stub to fix a bug where some functions

A single failed analyzer should not prevent others from reporting their
diagnostics. This is especially relevant as we work on updating
analyzers to support generic code.

Add an analyzer that checks for empty interfaces in constraint position,
that could instead use the new predeclared "any" type.

This adds an analyzer that provides suggested fixes for undeclared name
errors on function calls, implementing a stub of the fuction (with an
empty body). As of now this doesn't try to guess returned types but
only parameters.
Generated functions are appended at the end of the file where these type
errors occur.

This CL adds support for the Go 1.18 export format to iexport.go. This
support is based on cmd/compile/internal/typecheck/iexport.go, though
with a different types API and adjusted to build at Go versions below
1.18.
Specifically, this CL adds support for both column details in positions,
and generic types and functions. Along the way, some minor adjustments
are made to aid in debugging and testing.
Notably, after this CL the export data version produced by
go/gcexportdata will depend on the Go version used to build.
As part of this change, TestIExportData_stdlib is unskipped for Go 1.18.
