[dev.typeparams] cmd/compile: enable parsing of generic code with new -G flag

Browse source 
Providing the -G flag instructs the compiler to accept type parameters.
For now, the compiler only parses such files and then exits.

Added a new test directory (test/typeparam) and initial test case.

Port from dev.go2go branch.
