two small genxml changes
cd010fc4 genxml/gen_bits_header.py: Use regex to strip no alphanum chars
Makes this script slightly more efficient by turning a python loop into a regex replace.
I verified that the resulting output files match before and after the change.
4f23ab65 genxml: Remove extra space in gen4/45/5 field name
Remove extra space in field name. It get collapsed in output, so it doesn't have a big impact.
