[committed][libgomp, testsuite, openacc] Don't use const int for dimensions

[Tom de Vries]

Hi,

Const int is handled differently at -O0 for -xc and -xc++, which can cause noise
in testsuite/libgomp.oacc-c-c++-common test-cases (which are both run for c and
c++) if const int is used for launch dimensions.

Fix this by using #defines instead.

Committed to trunk.

Thanks,
- Tom

        * testsuite/libgomp.oacc-c-c++-common/reduction-1.c (ng, nw, vl): Use
        #define instead of "const int".
        * testsuite/libgomp.oacc-c-c++-common/reduction-2.c (ng, nw, vl): Same.
        * testsuite/libgomp.oacc-c-c++-common/reduction-3.c (ng, nw, vl): Same.
        * testsuite/libgomp.oacc-c-c++-common/reduction-4.c (ng, nw, vl): Same.
        * testsuite/libgomp.oacc-c-c++-common/reduction-5.c (ng, nw, vl): Same.
