Julian Brown 9316ad3b43 OpenMP/Fortran: Combined directives with map/firstprivate of same symbol 
This patch fixes a case where a combined directive (e.g. "!$omp target
parallel ...") contains both a map and a firstprivate clause for the
same variable.  When the combined directive is split into two nested
directives, the outer "target" gets the "map" clause, and the inner
"parallel" gets the "firstprivate" clause, like so:

  !$omp target parallel map(x) firstprivate(x)

  -->

  !$omp target map(x)
    !$omp parallel firstprivate(x)
      ...

When there is no map of the same variable, the firstprivate is distributed
to both directives, e.g. for 'y' in:

  !$omp target parallel map(x) firstprivate(y)

  -->

  !$omp target map(x) firstprivate(y)
    !$omp parallel firstprivate(y)
      ...

This is not a recent regression, but appear to fix a long-standing ICE.
(The included testcase is based on one by Tobias.)
