Subject: [PATCH 1/3] [OpenACC] Loop construct basic Sema and AST work
This patch implements the 'loop' construct AST, as well as the basic
appertainment rule. Additionally, it sets up the 'parent' compute
construct, which is necessary for codegen/other diagnostics.
A 'loop' can apply to a for or range-for loop, otherwise it has no other
restrictions (though some of its clauses do).

Subject: [PATCH 2/3] Change visitor to use 'traverse' instead of 'visit'
What I really wanted was for the visitor searching for loops to stop
searching at the loop/compute construct, not to stop entirely. The
traverse functions allow us to do that, whereas the visit just 'visit'.
This patch switches to traverse so we stop correctly.
