History
Akira Hatanaka 7c55265c2d [CodeGen] Fix a crash that occurs when a non-trivial C struct with a 
volatile array field is copied.

The crash occurs because method 'visitArray' passes a null FieldDecl to
method 'visit' and some of the methods called downstream expect a
non-null FieldDecl to be passed.

This reapplies r330151 with a fix to the test case.
