I don't know how to do this using "lnt", but you can do it more traditionally
by unpacking the LLVM nightly testsuite into llvm/projects, then configuring
LLVM with --with-externals=path/externals, where the externals directory is
expected to contain speccpu2000, speccpu2006 etc directories.  After building
LLVM you can (in the objects directory where you built LLVM) change to the
projects/test-suite subdirectory and do: make
This should build everything including SPEC.  Once it's done you can rummage
around to find the bitcode.

Ciao, Duncan.
