Add new immediate types for floating point and vector immediates. Use new immediates to define the constant value instructions in meta. Split the fconst instruction into two: f32const and f64const. This prevents confusion about the interpretation of 64 immediate bits when generating an f32 constant. Add an immvector ImmediateType. This immediate type is variable length, and provides all the bits of a SIMD vector directly.
