  1. [PowerPC] provide CFI for ELF32 to unwind cr2, cr3, cr4 

    Delete the code that skips the CFI for the condition register on
ELF32.  The code checked !MustSaveCR, which happened only when
Subtarget.is32BitELFABI(), where spillCalleeSavedRegisters is spilling
cr in a different way.  The spill was missing CFI.  After deleting
this code, a spill of cr2 to cr4 gets CFI in the same way as a spill
of r14 to r31.

Fixes llvm#83094
