[Libclc-dev] [PATCH 3/3] remquo: Flush denormals if not supported

[Jan Vesely via Libclc-dev]

It's OK to either flush to 0 or return denormal result if the device
does not support denormals. See sec 7.2 and 7.5.3 of OCL specs.
Fixes CTS on carrizo and turks.

Note: this is the last missing math builtin for GCN. (r600 still needs
sw fma implementation)
