Hi all,

I’m Patricio, and just joined the JVM team at Oracle last week. This is 
my first RFR which involves removing the experimental flags mentioned 
below. Could you please review this fix?

Summary: Removed NativeMonitorSpinLimit, NativeMonitorFlags and 
NativeMonitorTimeout experimental flags from globals.hpp and mutex.cpp 
and marked them as obsolete.
Note: Flags were removed so that code behaves as it was with 
experimental flags having their default values.

Bug URL: 
<https://bugs.openjdk.java.net/browse/JDK-8202615>https://bugs.openjdk.java.net/browse/JDK-8202615
Webrev URL: http://cr.openjdk.java.net/~coleenp/8202615.01/webrev/

The fix was tested with Mach5 on tiers 1, 2, 3, 4 and 5 on all platforms.

Since this is my first RFR it might need more examination :)

Thanks,
Patricio
