Detailed Description

@verbatim Lowering pass for OpenMP directives.  Converts OpenMP directives

into explicit calls to the runtime library (libgomp) and data marshalling to implement data sharing and copying clauses. Contributed by Diego Novillo dnovi.nosp@m.llo@.nosp@m.redha.nosp@m.t.co.nosp@m.m

Lowering of OpenMP parallel and workshare constructs proceeds in two
   phases.  The first phase scans the function looking for OMP statements
   and then for variables that must be replaced to satisfy data sharing
   clauses.  The second phase expands code for the constructs, as well as
   re-gimplifying things when variables have been replaced with complex
   expressions.

   Final code generation is done by pass_expand_omp.  The flowgraph is
   scanned for parallel regions which are then moved to a new
   function, to be invoked by the thread library.   

Context structure.  Used to store information about each parallel
   directive in the code.
