Andrew Wilkins bfb1679603 [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.

Andrew Wilkins b7394b22fd [llgo] Force exporting __morestack from llgoi
Summary:
Force exporting __morestack from llgoi, so that
the symbol is available to the execution engine
when linking with libLLVM.so. The engine does
not reference __morestack explicitly, so must
be provided by the host program.

Andrew Wilkins 4ffbbd7da7 [llgo] cmd/llgoi: use line editor
Summary:
This diff adds line-editing to llgoi, by
vendoring and using github.com/peterh/liner.
I have only implemented the basics here;
follow-ups will come later to add persisted
history, and completion,

Peter Collingbourne 38a7dde1c5 llgoi: Fix type identity for imported binary packages.
go/loader creates a fresh package map for each source package it imports. In
llgoi this caused binary imported packages to be imported anew for every input
line, resulting in spurious type errors and panics in go/ssa when encountering
previously imported types. Fix this by setting types.Config.Packages to our
internal package map.

Peter Collingbourne 6092d2c065 llgoi: Fix importing source packages together with dependent binary packages.
Note that this means that llgoi does not support the case
where a package's pkgpath is different from its import path,
but I don't think this should actually happen with llgoi.

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.
