Literals are now expressions, so in keeping with all the other
expression types, suffix the class name with Expression.
I'm not overly keen on requiring everything to have an Expression
suffix, but consistency is better than personal preference.
Note: this should have been part of 30848b6, but I managed to drop
this change instead of squashing it. Opps.

Just make Literal an expression. The ScalarConstructorExpression
provides no real value, aside from having a ConstructorExpression base
class that's common between ScalarConstructorExpression and
TypeConstructorExpression. TypeConstructorExpression will be folded into
CallExpression, so this hierarchy will serve no purpose.
First step in resolving the parser ambiguity of type-constructors vs
type-casts vs function calls.

The semantic nodes cannot be fully immutable, as they contain cyclic
references. Remove Resolver::CreateSemanticNodes(), and instead
construct and mutate the semantic nodes in the single traversal pass.
Give up on trying to maintain the 'authored' type names (aliased names).
These are a nightmare to maintain, and provided limited use.
Significantly simplfies the Resolver, and allows us to generate more
semantic to semantic references, reducing sem -> ast -> sem hops.
Note: This change introduces constant value propagation across constant
variables. This is unlocked by the earlier construction of the
sem::Variable.
