sinfo.ads, sinfo.adb (Alloc_For_BIP_Return): New flag to indicate that an allocator came from a b-i-p return statement.

2017-10-20  Bob Duff  <duff@adacore.com>

* sinfo.ads, sinfo.adb (Alloc_For_BIP_Return): New flag to indicate
that an allocator came from a b-i-p return statement.
* exp_ch4.adb (Expand_Allocator_Expression): Avoid adjusting the return
object of a nonlimited build-in-place function call.
* exp_ch6.adb (Expand_N_Extended_Return_Statement): Set the
Alloc_For_BIP_Return flag on generated allocators.
* sem_ch5.adb (Analyze_Assignment): Move Assert to where it can't fail.
If the N_Assignment_Statement has been transformed into something else,
then Should_Transform_BIP_Assignment won't work.
* exp_ch3.adb (Expand_N_Object_Declaration): A previous revision said,
"Remove Adjust if we're building the return object of an extended
return statement in place." Back out that part of the change, because
the Alloc_For_BIP_Return flag is now used for that.
