RFR(XS) 8074026: Deprecated UseBoundThreads, DefaultThreadPriority and NoYieldsInMicrolock VM options still defined in globals.hpp

[Dmitry Dmitriev]

Hello,

Please review this small fix for JDK-8074026. Also, I need a sponsor for 
this fix, who can push it.

Fix for JDK-8038473 deprecate UseBoundThreads, DefaultThreadPriority and 
NoYieldsInMicrolock VM options, but not remove them from 
src/share/vm/runtime/globals.hpp, so these options are still accepted by 
VM without warning. So, I remove these options from globals.hpp and also 
remove setting of deprecated UseBoundThreads when "-Xboundthreads" 
command line option is processed in src/share/vm/runtime/arguments.cpp.
