The Declaration in Sema::checkDeclIsAllowedInOpenMPTarget is incomplete. 

```
VarDecl 0x1582b278 <test3.c:6:1, col:7> col:7 ptr1 'int **'
`-OMPDeclareTargetDeclAttr 0x1582b2e0 <line:5:21> Implicit MT_To DT_Any 1
  `-<<<NULL>>>

```  
At this point, I do not have access to the initializer expression. Any suggestions?
