Assume in fewer places that the analysis is of a FunctionDecl, and initialize
the Environment properly for Stmts.
Moves constructors for Environment to header to make it more obvious that there
are only minor

Moves free functions from DataflowEnvironment.h/cc and
DataflowAnalysisContext.h/cc to RecordOps and a new ASTOps and exposes them as
needed for current use and to expose getReferencedDecls for out-of-tree use.

Exposes the collection functionality, but does not alter it beyond using a
return value instead of output parameters. Also relocates underlying and

…ng member pointers.
This initially landed with a broken test due to a mid-air collision with a new
requirement for Environment initialization before field modeling. Have added
that initialization in the test.
