As per issue #1196, the loop induction variable, which is an argument in the omp.wsloop operation, does not have a memory location, so when passed to a function or subroutine, the reference to the value is not a memory location, but the value of the induction variable. The callee function/subroutine is then trying to dereference memory at address 1 or some other "not a good memory location". This is fixed by creating a temporary memory location and storing the value of the induction variable in that. Test fixes as a consequence of the changed code generated. Add checking for some of the omp-unstructured.f90 to check for alloca, store and load operations, to ensure the correct flow. Add a test for CYCLE inside a omp-do loop. Also convert to use -emit-fir in the omp-unstructrued, and make the symbol matching consistent in the omp-wsloop-variable test.
