Semantic checks added to check the worksharing 'single' region closely nested inside a worksharing 'do' region. And also to check whether the 'do' iteration variable is a variable in 'Firstprivate' clause.
Files:
check-directive-structure.h
check-omp-structure.h
check-omp-structure.cpp
Testcases:
omp-do01-positivecase.f90
omp-do01.f90
omp-do05-positivecase.f90
omp-do05.f90

Most of the test cases added as part of this change contains semantic errors except few cases which are semantically correct but thrown a semantic error.
Currently flang is not throwing the errors for these cases and throwing semantic errors for the following correct test cases
{omp-do03.f90 , omp-loop-simd01.f90 , omp-simd02.f90 , omp-taskloop01.f90}
Hence, all the test cases are marked as XFAIL.
