rs6000.h (FIRST_PSEUDO_REGISTERS): Mention HTM registers in the comment.
* config/rs6000/rs6000.h (FIRST_PSEUDO_REGISTERS): Mention HTM
registers in the comment.
(DWARF_FRAME_REGISTERS): Subtract also the 3 HTM registers.
(DWARF_REG_TO_UNWIND_COLUMN): Use DWARF_FRAME_REGISTERS
rather than FIRST_PSEUDO_REGISTERS.
