Rebecca Stambler 94178a22b2 internal/lsp: use source.Offset instead of tok.Offset
This isn't strictly necessary for some of the cases, but it's better to
use it in all cases. Also added a test to ensure that we avoid
(*token.File).Offset in all of gopls--test was probably overkill, but it
was quick to write.

pjw 18fa840216 internal/lsp/semantic: prepare for generics
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
are misclassified as variables. This will be activated in a future CL,
as it will also change the golden test files.

This CL adds an initial draft of support for type parameters in the

 - the 'T' operator (type->type), which requires an integer operand and
   goes from *Named and *Signature types to the type parameter at the
   given index.
 - the 'C' operator (type->type), which goes from a *TypeParam type to
   its constraint.

Along the way, reorganize the path tests and update some errors messages
to consistently format the expected type with %T.

Pontus Leitzler 64bbad1f52 internal/lsp/debug: improve readability of session options
I find the session options page in gopls debug a bit hard to read. This
change aims to improve readability by:

- Sorting non-default options first (and alphabetically by name)
- Use bold text for option name
- Hide the "current value" if it's string representation equals the
  default value's string representation

Robert Findley 91c880c34d go/internal/gcimporter: add support for exporting the 1.18 export format
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.
