RFR (S) 8173715: Remove FlatProfiler

[Gerard Ziemski]

hi all,

(this is jdk part of the change, the hotspot part is being reviewed on hotspot-dev at openjdk.java.net)

The FlatProfiler (i.e. -Xprof) has been deprecated for a while, and now it’s the time to remove it.

Note about java's man page international translations: I was told by the localization team, that only changes to the English man pages are needed, and that they will trigger an update to other translations.

issue:  https://bugs.openjdk.java.net/browse/JDK-8173715
webrev: http://cr.openjdk.java.net/~gziemski/8173715_rev1_jdk

passes the following tests:

 JPRT
 RBT test_hotspot/test/serviceability/jvmti
 RBT test_hotspot/test/gc
 RBT test_hotspot/test/compiler
 RBT test_hotspot/test/runtime

Thank you.
