Expand RV32E demo support, prevent 'ebreak' looping (#883)

Browse source 
* Expand RV32E demo support, prevent 'ebreak' looping

The RegTest tests are modified in the Qemu and HiFive demos
to support RV32E and its limited set of registers.

'ebreak' call looping is removed in RegTest. This produces
a lot of noise when debugging.

* Correct whitespace

* Remove 'ebreak' instruction calls

The ebreak instruction sets and exception
which leads to jumping around the binary. This
can make debugging difficult.

* Fix whitespace formatting
