Benchmark results (make test TEST=micro:org.openjdk.bench.java.security.SecureRandomBench, pulling the benchmark from #98):

Before: 2972 ± 132  ns/op
 After:  490 ± 5 ns/op

[olivergillespie]

/approval request Performance improvement in SecureRandom.<init>, which I have seen on the hot path in real applications. Clean backport, low risk in my opinion (simple change to only one file). It has been in tip for around 4 weeks. Confirmed the benchmark results match tip (saves 2400ns in SecureRandom constructor).
