The constant transformer would only transform optional parameters,
since these are the only ones that can contain default values. This
caused it to miss annotations on required positional parameters.

JavaScript number semantics is currently implemented as the simplistic
version previously present in DDC. This is a starting point for fully
detailed JS number semantics.

This is needed so that we can publish a version of analyzer_plugin
that depends on it; also so that dartfmt work on "UI as code" features
can proceed.

Having a block as body instead of a list of expressions simplifies
code handling block expressions. Since it is always a block, it can
be left untagged in the serialized representation so the serialized
representation is not changed with this change.

Boolean operations are translated into explicit kernel nodes, so they
will not appear as method calls during constant evaluation.

When evaluating a constant expression, first evaluate all children.
If any of these turn out to be unevaluated, produce a partially
evaluated clone of the expression as a new unevaluated constant.
For lazy operators, if the left-hand side turns out unevaluated, the
right-hand side is included unmodified (not partially evaluated) in
the resulting unevaluated constant expression tree.
The implementation is optimized for the typical case of no unevaluated
constants. The intent is that the handling of unevaluated constants
introduces as little overhead as possible in this case.

To support separate compilation in DDC, the constant evaluator would
leave instantiations through unavailable constructors unevaluated.
These constructors were identified by being in an external library and
having no initializers. This check erroneously triggered on
"const Object()", breaking the bytecode generator.
