Change the run.go driver to recognize the "gc" build tag.
Change existing tests to use the "gc" build tag if they use some
feature that seems specific to the gc compiler, such as passing specific
options to or expecting specific behavior from "go tool compile".
Change tests to use the "!gccgo" build tag if they use "go build" or
"go run", as while those might work with compilers other than gc, they
won't work with the way that gccgo runs its testsuite (which happens
independently of the go command).

The general policy for the current state of js/wasm is that it only
has to support tests that are also supported by nacl.
The test nilptr3.go makes assumptions about which nil checks can be
removed. Since WebAssembly does not signal on reading a null pointer,
all nil checks have to be explicit.

This adds 8 bytes of binary size to every type that has methods. It is
the smallest change I could come up with for 1.7.
