The combination of pragma/aspect Inline_Always and -gnateV -gnata runs
afoul of the handling of inlining across units by gigi, which does not
inline a subprogram that calls nested subprograms if these subprograms
are not themselves inlined.
This condition does not apply to internally generated subprograms but
the special _postconditions procedure has Debug_Info_Needed set so it
is not considered as such and, as a consequence, triggers an error if
the enclosing subprogram requires inlining by means of Inline_Always.
The _postconditions procedure is already marked inlined when generating
C code so it makes sense to mark it inlined in the general case as well.
Tested on x86_64-pc-linux-gnu, committed on trunk
