The handling of overlapped structure mapping in CGOpenMPRuntime.cpp can lead to redundant zero-sized mapping nodes at runtime. This patch fixes it using a combination of approaches: trivially adjacent struct members won't have a mapping node created between them, and for more complicated cases (inheritance) the physical layout of the struct/class is used to make sure that elements aren't missed.

I've introduced a new class to track the state whilst iterating over the struct. This reduces a bit of redundancy in the code (accumulating CombinedInfo both during and after the loop), which I think is a bit neater.

This one though I'm not sure how to do -- the check lines for the new copy-gaps tests are manually written, as it appears were the check lines for the altered test target_map_codegen_35.cpp (which seems to be the only extant test that this patch affects). Would it be better to have auto-generated check lines for the whole generated output for the new tests? That seems like it'd be more brittle, to me.

… structs

The handling of overlapped structure mapping in CGOpenMPRuntime.cpp can
lead to redundant zero-sized mapping nodes at runtime.  This patch fixes
it using a combination of approaches: trivially adjacent struct members
won't have a mapping node created between them, and for more complicated
cases (inheritance) the physical layout of the struct/class is used to
make sure that elements aren't missed.

I've introduced a new class to track the state whilst iterating over
the struct.  This reduces a bit of redundancy in the code (accumulating
CombinedInfo both during and after the loop), which I think is a bit
neater.

Before:

Thanks. If it is not going to be an easy and quick fix, would you mind reverting the PR first and reland this PR once the error is fixed?
