ART: Add entrypoint and intrinsic for Math.pow().

MathBenchmarks.java#timePow results on taimen's little cores
fixed at frequency 1401600 with forced JIT compilation:
  - before:
    - X32: 356.33 (@FastNative), 315.39 (@CriticalNative)
    - X64: 357.31 (@FastNative), 315.37 (@CriticalNative)
  - after (LICM defeats the benchmark):
    - X32: 2.88
    - X64: 2.87
  - after but with kAllSideEffects to prevent LICM:
    - X32: 275.42
    - X64: 275.67

Test: Rely on TreeHugger.
