EPR #389586 - Add workaround for VI SPI SGPR initialization hardware bug for HSAIL path.

	There is a hardware bug in VI (UBTS502672) which requires a workaround. Compute shaders need to tell shader compiler the available sGPR is 78 and set sGPUR usage in the compiled ISA to be 94. It has been done in AMDIL path but not done in HSAIL path. This change will apply the workaround to HSAIL path.
