JDK-8025091 - VisibleMemberMap.java possible performance improvements
Description
The Javadoc benchmarks regress on most platforms (Linux, macOS, Solaris, Windows) in 10-b29.

Summary:
��� Tools-Javadoc-Jdk7       approx -1 to -3%
��� Tools-Javadoc-Jdk8       approx -2 to -6%
��� Tools-Javadoc-Startup   approx -2 to -5%
��� Tools-Javadoc-Steady   approx -2 to -6%

Regressions hold into subsequent releases.
VMswap results indicate the cause is in the JDK (not the JVM).
