[PATCH, OpenACC, 7/8] Multi-dimensional dynamic array support for OpenACC data clauses, libgomp support

Subject: [PATCH, OpenACC, 7/8] Multi-dimensional dynamic array support for OpenACC data clauses, libgomp support
Reply-to: <cltang at codesourcery dot com>

This part is the libgomp runtime handling for OpenACC dynamic arrays.

We handle such arrays by creating a "pointer block" that emulates the N-1 dimensions,
and then treating each data row of the final Nth dimension as an individual object
mapped in the TGT. All the rows are processed as appended after all the other map
kind objects.

Thanks,
Chung-Lin
