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.

Switch gofrontend to using go.googlesource.com, and
update to 81eb6a3f425b2158c67ee32c0cc973a72ce9d6be.
There are various changes required to update to the
go 1.5 runtime:
typemap.go is changed to accommodate the change in representation for equal/hash algorithms, and the removal of the zero value/type.
CMakeLists.txt is updated to add the build tree to the package search path, so internal packages, which are not installed, are found.
various files changes due to removal of __go_new_nopointers; the same change as in D11863, but with NoUnwindAttribute added to the added runtime functions which are called with "callOnly".
minor cleanups in ssa.go while investigating issues with unwinding/panic handling.

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.

Summary:
This diff is to support Debian packaging,
which sets various hardening-rleated flags
in CFLAGS. They don't make sense for Go,
so we just ignore them.

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.

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.

The new ABI is simpler for use cases such as dynamically loaded packages.
The calling convention for import functions is similar to what go/ssa would
produce if BareInits were cleared. However, simply clearing this flag causes
two additional issues:
1) We would need to special case the 'init$guard' variable (see
discussion in https://codereview.appspot.com/78780043/).
2) The call to __go_register_gc_roots needs to appear in the right
place, i.e. after the guard check. Making this check appear
in the right place with non-bare inits seems unreliable at best.
So we keep BareInits set and generate the necessary code manually.
It is still possible to get the old ABI by specifying a path to a gccgo
installation.

This change allows clients to generate IR using "files" received from locations
other than the file system. The regular file parser is moved to a new library,
"driver", which is intended to eventually contain much of the logic from
the existing driver.

multilib build and installs.
Summary:
This requires introducing a generated header to encapsulate the
LLVM_LIBDIR_SUFFIX value from the build system and push it into the go
code. From there, I've adjusted the gllgo code to systematically use
this rather than a raw "lib". This requires some awkwardness as one of
the flags *must* be "lib"-relative for compatibility with how gccgo
works. For that flag, we use ".." to back up a directory and then go
into the proper lib directory.
