RFR: 8341924: Improve error message with structurally malformed Code array

[Chen Liang]

Patch a tableswitch instruction's low value to be greater than a high value, previously, javap will not print any previous instruction and report problematic address/bci to be 0. This is because the iteration of bound models require first collecting all data into a buffer list. We call the eager `forEach` instead to avoid this problem.

Before:

$ javap -c BadSwitch.class
Compiled from "BadSwitch.java"
final class BadSwitch {
  static void work(int);
    Code:
Error: error at or after byte 0
}


Now:

$ $localjdk2/bin/javap -c BadSwitch.class
Compiled from "BadSwitch.java"
final class BadSwitch {
  static void work(int);
    Code:
       0: iload_0
Error: error at or after address 1: Invalid tableswitch values low: 9 high: 5
}
