When dealing with dispatch schedules (e.g.

dynamic, guided) we do not consider the lower and upper bound expressions generated by the worksharing loop support, but we use 0 and the iteration space size as constants

static

if the 'for' loop has a dispatch schedule (e.g.

dynamic, guided) then we need to use the LB and UB expressions generated by the worksharing code generation support, whereas in non combined situations we would just emit 0 and the LastIteration expression This function is necessary due to the difference of the LB and UB types for the RT emission routines for 'for_static_init' and 'for_dispatch_init'
