Please help review backport of JDK-8264752 related to JFR.
This backport also includes successive build failure fix JDK-8266206 (for older gcc version).

Applied almost cleanly on jdk11u, except copyright year in license and ClassFileInstaller build/use in test/jdk/jdk/jfr/startupargs/

Tested on Linux X64 tier1/tier2/tier3 release/fastdebug no regression. test/jdk/jdk/jfr test pass with release/fastdebug.
New test added in this PR also pass.
