// Conventions:
// - All temporary registers are float4s.
// - Scalar ops swizzle out a single component of their source registers denoted
// by 'a' or 'b'. src0.a means 'the first component specified for src0' and
// src0.ab means 'two components specified for src0, in order'.
// - Scalar ops write the result to the entire destination register.
// - pv and ps are the previous results of a vector or scalar ALU operation.
// Both are valid only within the current ALU clause. They are not modified
// when write masks are disabled or the instruction that would write them
// fails its predication check.
// Translates an ALU Vector/Scalar pair into HLSL fragments (Vector and Scalar ALU instructions
// are ALWAYS executed in pairs, and are part of the same instruction definition.
