[PATCH v1 4/8] new contrib/generate_all.sh: batch risugen script

["Alex Bennée" <alex.bennee@linaro.org>]

This is a simple script for generating all instructions in a given
RISU file. You can split up the batch size by passing a -n N command
line options. For example:

  ./contrib/generate_all.sh -n 2 hp.risu testcases.armv8.2_hp
