Handle multi-word regsiters in REG_CFA_RESTORE notes

[Bernd Schmidt]

While testing the altest iteration of shrink-wrapping on mips-elf, a new
failure showed up in gcc.dg/pr43139.c. When restoring floating-point
registers, we attach REG_CFA_RESTORE notes for DFmode registers, but the
dwarf2cfi code only records a single regno for such a multiword hard reg.

Fixed with this patch, tested with shrink-wrapping on mips-elf (default
multilib plus two with -mips16). Ok?
