This CL makes two related changes: 1. It uses 'go env -json' to query the environment configuration, rather than attempting to manually reconstruct the values that cmd/go is going to use. 2. It changes the -goexperiment flag to *extend* any ambient GOEXPERIMENT configuration. Notably, this means that '-goexperiment fieldtrack' now tests fieldtracking in conjunction with any other experiments (e.g., unified IR). Tests that want to test an exact GOEXPERIMENT config should use '-goexperiment none,foo' instead.
