The current implementation uses LD_VAR_BUF[_IMM] to look up varyings, which limits the number of varying components to 64 due to an 8-bit offset value. As this does not align to maxVertexOutputComponents (128), this change replaces the use of LD_VAR_BUF[_IMM] with LD_VAR[_IMM] + Attribute Descriptors, which do not have this limitation. As allocating Attribute Descriptors is potentially expensive, this can be further optimized by falling back to LD_VAR_BUF[_IMM] in cases where we can ensure we do not use more than 64 varying components. This change currently does not change behavior for gallium/panfrost, though that should be done as well.
