GNAT-defined Ada extensions are divided into two categories: those that are
enabled by either -gnatX or -gnatX0 and those which require -gnatX0.
Move static intrinsic functions from the second category into the first.

* doc/gnat_rm/implementation_defined_pragmas.rst: Add the standard
'... "On" enables this extension.' sentence to the description of
static intrinsic functions.
* sem_ch13.adb
(Analyze_Aspect_Spec): In the call to Error_Msg_GNAT_Extension for
a Static aspect specification for an intrinsic function, specify
Is_Core_Extension => True.
* sem_eval.adb
(Eval_Intrinsic_Call): Test Core_Extensions_Allowed instead of
testing All_Extensions_Allowed.
* gnat_rm.texi: Regenerate.

in particular the ``Shift_Left`` and ``Shift_Right`` intrinsics.

* ``[]`` aggregates
This new aggregate syntax for arrays and containers is provided under -gnatX
functions and the compiler will evaluate some of these intrinsic statically,
in particular the @code{Shift_Left} and @code{Shift_Right} intrinsics.
+An Extensions_Allowed pragma argument of “On” enables this extension.
