Fix uninitialized variable with nested variant record types
This fixes a wrong code issue with nested variant record types: the
compiler generates move instructions that depend on an uninitialized
variable, which was initially a SAVE_EXPR not instantiated early enough.
gcc/ada/ChangeLog:
* gcc-interface/decl.c (build_subst_list): For a definition, make
sure to instantiate the SAVE_EXPRs generated by the elaboration of
the constraints in front of the elaboration of the type itself.
gcc/testsuite/ChangeLog:
* gnat.dg/discr59.adb: New test.
* gnat.dg/discr59_pkg1.ads: New helper.
* gnat.dg/discr59_pkg2.ads: Likewise.
