8046268: compiler/whitebox/ tests fail : must be osr_compiled
Summary: Added code to 'warm up' the methods before triggering OSR compilation by executing them a limited number of times. Like this, the profile information marks the loop exit as taken and we don't add an uncommon trap.

8059758: Footprint regressions with JDK-8038423
Summary: Changes in JDK-8038423 always initialize (zero out) virtual memory used for auxiliary data structures. This causes a footprint regression for G1 in startup benchmarks. This is because they do not touch that memory at all, so the operating system does not actually commit these pages. The fix is to, if the initialization value of the data structures matches the default value of just committed memory (=0), do not do anything.
