[committed][libgomp, testsuite, openacc] Remove -foffload=-w in reduction-[1-5].c

[Tom de Vries]

Hi,

Before the commit "[libgomp, testsuite, openacc] Don't use const int for
dimensions", the "const int" construct was used to set launch dimensions in
reductions-[1-5].c.  In the case of -xc -O0, the const int is implemented as a
variable by the C front-end.  Consequently, the nvptx back-end generated
warnings that vector_length was overridden to be hard-coded, rather than left to
be set at runtime.  The test-cases silenced these warnings by switching off all
warnings in the accelerator compiler using "-foffload=-w".

Given that no warnings occur anymore, remove the "-foffload=-w" setting.

Committed to trunk.

Thanks,
- Tom
