Or don't use it all, it is too heavy.  It is better to use something light.  I
added this code on early stages of LRA development because it is hard to
predict what RTL could be.  Most important check before was one on addresses
and it is gone.  Insn_invalid_p check is just a paranoid check.  If something
goes wrong, the current LRA catches it later in any case.

I hope to fix it today.
