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.
