* exp_ch6.adb (Expand_N_Extended_Return_Statement): Do not call
SS_Release for a block statement enclosing the return statement in the
case where a build-in-place function return is returning
the result on the secondary stack. This is accomplished by

already set correctly for blocks in the non-build-in-place case
(in Expand_Simple_Function_Return).

the Set_Sec_Stack_Needed_For_Return calls. Called in the
