RFR: 8361102: java.lang.classfile.CodeBuilder.branch(Opcode op, Label target) doesn't throw IllegalArgumentException - if op is not of Opcode.Kind.BRANCH

[Chen Liang]

Currently, DirectCodeBuilder is erroneously missing argument checks for a few of its override methods that take arguments such as Opcode and the array size for multianewarray and the switches, which would write something before throwing an exception. We correct these problems and verify with some tests.

Note: Other Label-writing methods resolve their label eagerly so they are not (yet) problematic.
