internal/lsp/source: improve completion support for args to builtins
We now understand what "kind" of type is expected when using various
builtins. For example, when completing "close(<>)" we prefer channels,
and when completing "delete(<>)" we prefer maps.
I also added some code to infer the expected type for the second
argument to "delete()" and for the args to "copy()":
delete(map[someType]int{}, <>) // expect "someType"
copy([]int{}, <>) // expect "[]int"
copy(<>, []int{}) // expect "[]int"
And I marked "new()" as expected a type name, and it infers the type
name properly:
var _ *int = new(<>) // expected type at "<>" is "int"
Fixes golang/go#36326.

This subrepository holds the source for various packages and tools that support the Go programming language.
Some of the tools, godoc and vet for example, are included in binary Go distributions.
Others, including the Go guru and the test coverage tool, can be fetched with go get.
Packages include a type-checker for Go and an implementation of the Static Single Assignment form (SSA) representation for Go programs.
The easiest way to install is to run go get -u golang.org/x/tools/.... You can also manually git clone the repository to $GOPATH/src/golang.org/x/tools.
This repository uses Gerrit for code changes. To learn how to submit changes to this repository, see https://golang.org/doc/contribute.html.
