Dan Scales dca9c11845 cmd/compile: add support for generic channels and type conversion during calls
Add support for channels in subster.typ(). Add new test file chans.go.

To support assignability of bidirectional channel args to directional
channel params, I needed to type check generic calls after they are
instantiated. (Eventually, we will create separate functions to just do
the assignability logic, so we don't need to call the old typechecker in
this case.) So, for generic calls, we now leave the call as OCALL (as a
signal that the call still needs typechecking), and do typecheck.Call()
during stenciling.

Smaller changes:
 - Set the type of an instantiated OCLOSURE node (and not just the associated
   OFUNC node)

 - In instTypeName2, filter out the space that types2.TypeString inserts
   after a common in a typelist. Our standard naming requires no space
   after the comma.

 - With the assignability fix above, I no longer need the explicit
   conversions in cons.go.

zerodivide.go

The test directory contains tests of the Go tool chain and runtime. It includes black box tests, regression tests, and error output tests. They are run as part of all.bash.

To run just these tests, execute:

../bin/go run run.go

To run just tests from specified files in this directory, execute:

../bin/go run run.go -- file1.go file2.go ...

Standard library tests should be written as regular Go tests in the appropriate package.

The tool chain and runtime also have regular Go tests in their packages. The main reasons to add a new test to this directory are:

  • it is most naturally expressed using the test runner; or
  • it is also applicable to gccgo and other Go tool chains.
