rs6000: Debug regnums for TM registers

Browse source 
Since GCC 8, we have output incorrect numbers for the transactional
memory registers.

Also, we didn't output the correct DWARF register numbers for those.
The number for sprN is 100+N.

This fixes both these issues.


	* config/rs6000/rs6000.c (rs6000_dbx_register_number): Return the
	correct numbers for TFHAR, TFIAR, TEXASR.
