When unpacking a std::tuple we know that the std::get calls are

We also know the std::get calls won't throw for a std::array, but this

throw, and so just use a potentially-throwing noexcept-specifier.

This patch corrects several bugs within the compiler which led to
inconsistent handling of compile time Constraint_Errors. Notibly,
subtype out of range checks which are only out of range of the subtype
must be warnings while out of range checks where the value is out of
range of the base type must be an error. Also, type conversions and
qualified expressions on literals constitute errors on any out of range
value. The compiler needed many of these cases clarified.

This gets rid of redundant range checks generated in 5 out of the 9
cases of scalar conversions, i.e. (integer, fixed-point, floating-point)
converted to (integer, fixed-point, floating-point).
The problem is that the Real_Range_Check routine rewrites the conversion
node into a conversion to the base type so, when its parent node is
analyzed, a new conversion to the subtype may be introduced, depending
on the context, giving rise to a second range check against the subtype
bounds.
This change makes Real_Range_Check rewrite the expression of the
conversion node instead of the node, so that the type of the node is
preserved and no new conversion is introduced. As a matter of fact,
this is exactly what happens in the float-to-float case which goes to
the Generate_Range_Check circuit instead and does not suffer from the
duplication of range checks.
For the following procedure, the compiler must now generate exactly one
range check per nested function:
procedure P is
type I1 is new Integer range -100 .. 100;
type I2 is new Integer range -200 .. 200;
type D1 is delta 0.5 range -100.0 .. 100.0;
type D2 is delta 0.5 range -200.0 .. 200.0;
type F1 is new Long_Float range -100.0 .. 100.0;
type F2 is new Long_Float range -200.0 .. 200.0;
function Conv (A : I2) return I1 is

This fixes a small glitch in Insert_Valid_Check, which needs to
propagate the Do_Range_Check flag onto the rewritten expression, but
uses its Original_Node as the source of the copy. Now Original_Node
does not necessarily point to the node that was just rewritten, but to
the ultimately original node, which is not the same node if the

This change prevents the analysis phase of the front-end from setting

because the expansion phase would not be able to generate the check.
This pattern appears in the ancient DEC Starlet package and it doesn't
seem to be useful at this point to change the expander to deal with it,
so instead the analysis phase is adjusted. Morever the compiler already
issues a warning in this case so this is probably good enough.

The expression that caused the ICE
++(a += 1.0);
The D front-end rewrites and applies implicit type conversions so the
expression gets simplified as
(int)((double) a += 1.0) += 1
The codegen pass would subsequently generate the following invalid code
(int)(double) a = (int)((double) a + 1.0) + 1
The LHS expression `(int)(double) a', represented as a FIX_TRUNC_EXPR
being what trips as it is not a valid lvalue for assignment.
While LHS casts are stripped away, convert_expr adds a double cast
because it converts the expression to its original type before
converting it to its target type. There is no valid reason why this is
done, so it has been removed.
