Hexagon (target/hexagon/*.py): raise exception on reg parsing error

Currently, the python scripts used for the hexagon building will not
abort the compilation when there is an error parsing a register. Let's
make the compilation properly fail in such cases by rasing an exception
instead of just printing a warning message, which might get lost in the
output.

This patch was generated with:

 git grep -l "Bad register" *hexagon* | \
 xargs sed -i "" -e 's/print("Bad register parse: "[, ]*\([^)]*\))/hex_common.bad_register(\1)/g'

Plus the bad_register() helper added to hex_common.py.
