You mean -fno-lra, and s/IRA/LRA/, right?  I think the reason for no
compiler switch is that while returning false from ix86_lra_p ()
likely works right now, -fno-lra mode would be yet another
thing to support.  So, for investigations just return false from ix86_lra_p,
similarly for benchmarking, but as it needs compiler source changes, it is
obvious that with old reload everybody is on their own if it breaks
for targets that switched to LRA.
