This builds on the VM's support for constants, and brings dartdevk to
parity with dartdevc. Also, constants are computed with arithmetic
operations that match runtime behavior (JS numbers).
Constants are limited in some cases right now: when building outline
kernel files (via pkg/dev_compiler/tool/build_pkgs.dart), constant field
initializers are not preserved, and this fact is not recorded, making
these fields appear to be implicitly null. dartdevk will recognize this
and avoid inlining the constant in these cases.
