This adds FileUriConstantExpression, a subclass of ConstantExpression, to support correct file offset of annotations for augmentations and patches.
The FileUriExpression is used to carry the file uri of the expression
before constant evaluation.

This changes the pattern lowering to use unchecked AsExpression
instead of promoted VariableGet when this occurs within a late
cache variable initializer. This is done to avoid promoted variables
that violate the (otherwise used) conservative reasoning about the
execution order of closures.
The unchecked AsExpressions are now shown in the ast-to-text.

Looking at instructions this seems to speedup compilation of
`compile.dart` with about 1.00% in AOT mode.
Occasionally there's also a measurable time improvement, e.g.
```
msec task-clock:u: -1.3447% +/- 1.1644%
seconds time elapsed: -1.3438% +/- 1.1638%
seconds user: -1.8838% +/- 1.4478%

If enum values have used defined fields that use fromEnvironment constants
the enum values themselves are seen as unevaluated constants when
compiling with dart2js. This means that the enum value are not recognized
correctly in exhaustiveness checking.
This CL changes the enum value representation of the CFE to use the
enum class and the name of the enum element, derived either from the
instance constant or the unevaluated constant expression.

When compiling "compile.dart" the type given to computeNonNull

When compiling compile.dart:
148,192 FunctionType are created via `computeThisFunctionType`.
133,085 of them have no named parameters; 141,507 of them have no type
parameters; 128,357 of them have neither.
This CL makes it not create new lists when not needed
(or create empty iterators and sort empty lists), and makes the lists
it do create not growable.

This CL splits up `Reference.node` in to the most-often fast-case and the
has-to-load case, making the procedure smaller which makes the VM inline
it. This was "verified" by looking at the VMs optimized flow graph for
`Reference.asClass`.
This CL furthermore reduces the number of "calls" to `Reference.node`
by almost half (a reduction of over 3 mio calls when compiling
`compile.dart`) by "caching" the `.node` call in the `as*` methods.

There is an `includeSources` option today to skip writing both source bytes as well as the line starts. Dart2JS needs the line starts to generate source maps from its modified dill. But the actual bytes aren't used passed a certain point. This new option would allow us to exclude the information we don't need from the dill.
For large applications this can reduce the size of the dill by close to 50%.
