Fixes example 37 on Windows using AMD GCN 1.0 gpus (#2232)

Browse Source 
When compiling shader cs_gdr_stream_compaction.sc on GCN 1.0 gpus
the following error appears:

Compute link error: HW_UNSUPPORTED.
ERROR: Internal compile error, error code: E_SC_NOTSUPPORTED
Shader not supported by HW

These changes avoid the error.
