arch-arm: Adding isa templates for semihosting ops

A new class of Semihosting constructor templates has been added.  Their
main purpose is to check if the Exception Generation Instructions (HLT,
SVC) are actually a semihosting command.  If that is the case, the
IsMemBarrier flag is raised, so that in the O3 model we perform a
coherent memory access during the semihosting operation.
