[gomp5] Fix ICE on clauses-1.c testcase

[Jakub Jelinek]

Hi!

Another thing I've missed in the testing (or lack thereof) of the
task reduction parsing patch.  Reduction is a data sharing clause
that is best located on the task construct for the taskloop IL sandwich,
it will be of course added as argument to the GOMP_taskloop call
when implemented later.

Regtested on x86_64-linux, committed to gomp-5_0-branch.

	* gimplify.c (gimplify_omp_for): Move OMP_CLAUSE_REDUCTION
	and OMP_CLAUSE_IN_REDUCTION from taskloop to the task construct
	sandwiched in between two taskloops.
