The problem is that we don't revert the df flags back.
This patch fixes it by clearing DF_DEFER_INSN_RESCAN after
calling df_process_deferred_rescans, so that it doesn't leak into following
unprepared passes that expect non-deferred rescans.

* config/i386/i386-features.c (remove_partial_avx_dependency): Clear
DF_DEFER_INSN_RESCAN after calling df_process_deferred_rescans.
* gcc.target/i386/20051216-1.c: New test.
