1a2fa2f821 When lra-remat rematerializes an instruction with a clobber, it checks that the clobber does not kill live registers. 
When lra-remat rematerializes an instruction with a clobber, it checks
that the clobber does not kill live registers.  However it fails to check
that the clobber also doesn't overlap with the destination register of the
final rematerialized instruction.  As a result it is possible to generate
illegal instructions with the same hard register as the destination and a
clobber.  Fix this by also checking for overlaps with the destination
register.

6938e7f1d8 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.
