Using mechanisms added in previous CLs, this change modifies the m5
utility so that it can use any of the back ends enabled and implemented
by each variant, defaulting to one particular implementation if not is
selected explicitly.
On x86, the default mechanism is the magic address. All other variants
default to the magic instruction since they don't have a well
established address to use or even in most cases an implementation to
use.
The ability to override the particular magic address the utility wants
to use (necessary on variants such as aarch64) will be added in a future
CL.

It may be the case that each item M5OP_FOREACH iterates over should end
in a ',' and not a ';', for instance when putting each item into an
array or initializing a structure. If the caller still wants a ';', they
can add it into the definition of the M5OP macro.
