RFR: 8281472: JVM options processing silently truncates large illegal options values

[Harold Seigel]

Please review this change to fix JDK-8281472.  The fix prevents truncation of large illegal option values by rejecting those values if they exceed the range of their type.  For example, it rejects values of int options that are not between max_int and min_int.

The fix was tested by running Mach5 tiers 1-2 on Linux, Mac OS, and Windows, and Mach5 tiers 3-5 on Linux-x64 and Windows-x64.

Thanks, Harold
