AMDGPU/SI: Add new target attribute InitialPSInputAddr
Summary:
This allows Mesa to pass initial SPI_PS_INPUT_ADDR to LLVM.
The register assigns VGPR locations to PS inputs, while the ENA register
determines whether or not they are loaded.
Mesa needs to set some inputs as not-movable, so that a pixel shader prolog
binary appended at the beginning can assume where some inputs are.
v2: Make PSInputAddr private, because there is never enough silly getters
and setters for people to read.
