Function `dmd.funcsem.modifyReturns`

Modify all expression type of return statements to tret.


						
				void modifyReturns
				(
				

				  FuncLiteralDeclaration fld,
				

				  dmd.dscope.Scope* sc,
				

				  Type tret
				

				);

On function literals, return type may be modified based on the context type after its semantic3 is done, in FuncExp::implicitCastTo.

A function() dg = (){ return new B(); } // OK if is(B : A) == true

If B to A conversion is convariant that requires offseet adjusting, all return statements should be adjusted to return expressions typed A.
