6986863: ProfileDeferralMgr throwing ConcurrentModificationException

[jankratochvil]

It is needed in jdk8 as a prerequisite for JDK-8347377.
A testcase is included.
It is not a clean backport - source files are moved, copyright years update, original patch uses extra function getStandardProfileInputStream(), Anton Voznia hasn't implemented it by himself, he borrowed it from another patch https://bugs.openjdk.org/browse/JDK-8039271 and changed it a bit according to the requirements. He didn't include entire fix because it's redundant.
This backport is authored by Anton Voznia, I am only submitting it. Anton Voznia is an Azul employee so he should be covered by Azul OCA. Anton Voznia has not signed a personal OCA from Oracle.
It requires #690 as a prerequisite.
