I'm now having design question about setting the correct implicit map type in
Sema for the below situation:
```
int *ptr_1, *ptr_2, arr[50];
#pragma omp target defaultmap(alloc:pointer) defaultmap(from:aggregate)
{
ptr_1++, ptr_2++;
arr[0]++;
}
```
In this case we need to store two maptypes - alloc and from for an
`ActOnOpenMPMapClause` but `ActOnOpenMPMapClause` only pass one maptype so I'm
wondering should I modify the interface of OMPMapClause which pass an array of
maptypes rather than one maptype variable?

SourceLocation DefaultAttrLoc;
- DefaultMapAttributes DefaultMapAttr = DMA_unspecified;
- SourceLocation DefaultMapAttrLoc;

Not sure about this one. I've already put DMVC_unspecified to the last one in
the DefaultMapVariableCategory enum so that I now don't need magic number. Or
you are pointing something else? Thanks
