RFR (M): 8138983: Runtime: implement ranges for Shared*** flags

[gerard ziemski]

hi all,

Please review this final fix for JEP-245

We implement the remaining runtime flags in the Shared* family.

Summary of changes:

#1 core fix - we factor out the constants to be used in the ranges

src/share/vm/classfile/compactHashtable.cpp
src/share/vm/memory/metaspace.cpp
src/share/vm/memory/metaspaceShared.hpp
src/share/vm/runtime/globals.hpp


#2 we increase default sizes of range and constraint tables to minimize mallocs

src/share/vm/runtime/commandLineFlagConstraintList.cpp
src/share/vm/runtime/commandLineFlagRangeList.cpp


#3 we fix a bug that I run into the OptionsValidation test framework while working

test/runtime/CommandLine/OptionsValidation/common/optionsvalidation/IntJVMOption.java


#4 we add functionality to OptionsValidation test framework that we later use

test/runtime/CommandLine/OptionsValidation/common/optionsvalidation/JVMOptionsUtils.java


#5 we cleanup and extend the existing test to detect a case where we get out of range value

test/runtime/SharedArchiveFile/LimitSharedSizes.java


The fix passes RBT "hotspot/test/:hotspot_all,testlist,noncolo.testlist --add-tonga-keyword quick” and JPRT “hotspot" tests
