gollvm: support reading from stdin (command line flag "-")

Add support for reading Go source code from stdin if the "-" command
line flag is specified. For compatibility with gccgo, support the
limited use case of "-x c -" provided that standard input is actually
empty (the Go tool invokes gccgo in some instances passing "-x c" when
detecting whether a given flag is supported).
