Ugh, this is slightly non-trivial.  The C++ cloning does not properly clone
DECL_VALUE_EXPR because we do not bother to do this from copy_body_r.

Confirmed.  Somehow another DECL_VALUE_EXPR issue

test::test() (struct test * const this)
{
  union ._0 D.2124;
  char pngpal[1] [value-expr: D.2119.pngpal];
  char * D.2127;

  # BLOCK 2
  # PRED: ENTRY (fallthru)
  D.2127_1 = D.2119.pngpal[0];
  xread (D.2127_1);
  return;

there is no D.2119 anymore - it gets replaced with D.2124 duing gimplification.
