Introduce llgoi, a REPL for Go llgoi is a Go REPL based on llgo irgen and the LLVM JIT. It supports expressions, statements, most declarations and imports, including binary imports from the standard library and source imports from $GOPATH.

[llgo] llgoi: separate evaluation from printing Summary: Separate the evaluation of expressions from printing of results. This is in preparation for splitting the core of the interpreter out for use in alternative interpreter frontends. At the same time, the output is made less noisy in response to comments on the golang-nuts announcement. We would ideally print out values using Go syntax, but this is impractical until we have libgo based on Go 1.5. When that happens, fmt's %#v will handle reflect.Value better, and so we can fix/filter type names to remove automatically generated package names.
