* exp_util.ads, exp_util.adb:
This patch replaces a number of occurrences of explicit tests for N_Null
with calls to Known_Null. This improves tracking of null values, since
Known_Null also catches null constants, and variables currently known to
be null, so we get better tracking.
(Ensure_Defined): create an itype reference only in the scope of the
itype.
(Side_Effect_Free): A selected component of an access type that
denotes a component with a rep clause must be treated as not
side-effect free, because if it is part of a linked structure its
value may be affected by a renaming.
(Expand_Subtype_From_Expr): For limited objects initialized with build
in place function calls, do nothing; otherwise we prematurely introduce
an N_Reference node in the expression initializing the object, which
breaks the circuitry that detects and adds the additional arguments to
the called function. Bug found working in the new patch for statically
allocated dispatch tables.
(Is_Library_Level_Tagged_Type): New subprogram.
(Remove_Side_Effects): If the expression of an elementary type is an
operator treat as a function call.

attributes properly to compute the constraint on the resulting aggregate
which is a string.

Thunk_Alias which is no longer required, cleanup evaluation of the
the controlling type, and update the documentation.
Replace occurrence of Default_Prim_Op_Count by
Max_Predef_Prims. Addition of compile-time check to verify
that the value of Max_Predef_Prims is correct.
(Check_Premature_Freezing): Apply check in Ada95 mode as well.

of the primary tag. Remove generation of tags (now done by Make_Tags).
Additional modifications to handle non-static generation of dispatch
tables. Take care of building tables for asynchronous interface types
(Make_Tags): New subprogram that generates the entities associated with

declaration of the primary tag that will be declared later by Make_DT.

Initialize or Normalize_Scalars is set.
