This patch fixes/improves check for valid insn in newly introduced
ADJUST_INSN_LENGTH.
(Please note that other targets (e.g. aarch64) needs similar fix. MIPS
could use NONDEBUG_INSN_P instead of INSN_P there.)

* config/i386/i386.h (ADJUST_INSN_LENGTH): Use NONDEBUG_INSN_P (INSN)
predicate and INSN_CODE (INSN) >= 0 to check for valid instruction.
Bootstrapped and regression tested on x86_64-linux-gnu {,-m32} with
--enable-checking=rtl. Also, I have started bootstrap with
--enable-checking=valgrind, but it will probably finish sometime in
the next ice age.
Committed to mainline SVN.
Uros.
