An invalid constant is (currently) represented by an unevaluated
invalid expression. Using this instead of null fixes 63 out of 125
CFE constant-evaluation crashes with constant-update-2018 and
correctly signals 26 more previously-missed compile-time errors.

Fasta allows some non-const static field access in constant contexts
which leads to the constant evaluator trying to evaluate them. Signal
an error instead of crashing. This will double-report errors for the
cases that Fasta already catches, and we should fix that
double-reporting.
Fix unbounded recursion in printing unevaluated constants (writeNode
called visitUnevaluatedConstant which called defaultConstant which
called writeNode...).

Make the constant evaluator take an explicit error reporter so we have
to opt in to using the "simple" one that reports errors in an ad hoc
way. This is the start of a change to use Fasta-controlled error
messages throughout and eventually get rid of the simple error
handler, and to continue constant evaluation after the first constant
error.

Add Kernel syntactic support for constants constructed by
bool.fromEnvironment, int.fromEnvironment, and String.fromEnvironment.
These values are not necessarily available at compile time. Because
constants can depend on these values, there is also an unevaluated constant
that represents an expression depending on environment values.
This syntax is not yet produced by the Fasta compiler.

Instead, delimit lists. The empty list is naturally ().
