RFR 8189208: Cleanup ancient argument processing code

[Harold Seigel]

Hi Gerard,

The change looks good but I have one question.

What's the purpose of this change in jvm.h ?

@@ -1277,20 +1277,19 @@
  typedef struct {
      unsigned int jdk_version; /* Encoded $VNUM as specified by JEP-223 */
      unsigned int patch_version : 8; /* JEP-223 patch version */
      unsigned int reserved3 : 8;
      unsigned int reserved1 : 16;
- unsigned int reserved2;
+ unsigned int reserved2 : 2;

Thanks, Harold
