code[x_, y_, z_] := If[LessEqual[x, -5.0], N[(x * z), $MachinePrecision], If[LessEqual[x, 202000000.0], N[(5.0 * z), $MachinePrecision], N[(x * z), $MachinePrecision]]]

Derivation

1. Split input into 2 regimes

2. if x < -5 or 2.02e8 < x

   1. Initial program 99.9%

      \[x \cdot \left(y + z\right) + z \cdot 5 \]

   2. Taylor expanded in z around inf

      \[\leadsto \color{blue}{z \cdot \left(5 + x\right)} \]

   4. Applied rewrites 62.6%

      \[\leadsto \color{blue}{z \cdot \left(5 + x\right)} \]

   5. Taylor expanded in x around inf

      \[\leadsto x \cdot \color{blue}{z} \]

   7. Applied rewrites 27.5%

      \[\leadsto x \cdot \color{blue}{z} \]

   if -5 < x < 2.02e8

   1. Initial program 99.9%

      \[x \cdot \left(y + z\right) + z \cdot 5 \]

   2. Taylor expanded in x around 0

      \[\leadsto \color{blue}{5 \cdot z} \]

   4. Applied rewrites 37.4%

      \[\leadsto \color{blue}{5 \cdot z} \]
3. Recombined 2 regimes into one program.
4. Add Preprocessing

Alternative 9: 27.5% accurate, 3.1× speedup
