[OpenACC]Reimplement 'for' loop checks for a loop construct

The 'loop' construct has some pretty strict checks as to what the for
loop associated with it has to look like. The previous implementation
was a little convoluted and missed implementing the 'condition'
checking.  Additionally, it did a bad job double-diagnosing with
templates.

This patch rewrites it in a way that does a much better job with the
double-diagnosing, and proeprly implements some checks for the
'condition' of the for loop.
