Log:
rs6000: Fix for separate shrink-wrapping for fp (PR80860, PR80843)

After my r248256, rs6000_components_for_bb allocates an sbitmap of size
only 32 while it can use up to 64.  This patch fixes it.  It moves the
n_components variable into the machine_function struct so that other
hooks can use it.


PR bootstrap/80860
PR bootstrap/80843
* config/rs6000/rs6000.c (struct machine_function): Add new field
n_components.
(rs6000_get_separate_components): Init that field, use it.
(rs6000_components_for_bb): Use the field.

Note that GCC bootstraps successfully with r248317, prior to richi's change

* df-scan.c (df_insn_refs_verify): Speedup when not verifying.

I will try after the sws patch, but, if not, there is something wrong with
richi's patch.

But I had a successful bootstrap with r248295, which is after your patch.

It is memory corruption.  PR80843 may be the same.

It is caused by my r248256, sws for FP.

I have a patch.  What a silly bug.
