a cursory examination of dwarf2out.c shows that the calls of
DWARF2_FRAME_REG_OUT are related to either dw_cfi_oprnd1 or dw_cfi_oprnd2
depending on the location. I don't see changes associated to r157762 making
sure that the existing DWARF2_FRAME_REG_OUT calls were corrected for the
reversal of the operands.
