LFCaching causes bulk nashorn performance regression on SPARC.
Here is data, comparing 8u40-b05(no lfcaching) vs 8u40-b19.
1. nasnorn with optimistic typing:
<benchmark> <perf regression in percentage>
Box2d 157.46%
Crypto 18.37%
Gbemu 71.36%
NavierStokes 27.59%
Raytrace 72.39%
Richards 11.76%
2. 1. nasnorn without optimistic typing:
<benchmark> <perf regression in percentage>
Box2d 340.24%
Richards 18.83%
