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.
