This entails marking the pragma as requiring an lvalue and explicitly going
to the corresponding variable of the constants, which is always built since
the front-end marks the constants as having their address taken.
Tested on x86_64-pc-linux-gnu, committed on trunk

* gcc-interface/trans.c (lvalue_required_p) <N_Pragma>: New case.
<N_Pragma_Argument_Association>: Likewise.
(Pragma_to_gnu) <Pragma_Inspection_Point>: Fetch the corresponding
variable of a constant before marking it as addressable.diff --git a/gcc/ada/gcc-interface/trans.c b/gcc/ada/gcc-interface/trans.c
