David Stuttard 69f7d81d0a [AMDGPU] Set number vgprs used in PS shaders based on input registers actually used ...

For PS shaders we can use the input SPI_PS_INPUT_ENA and SPI_PS_INPUT_ADDR
registers

Calculate the number of VGPR registers used as input VGPRs based on these
registers rather than the arguments passed in (this conservatively always
allocates the maximum).
