0f8f7577a5 Don't create an intermediate stylesheet for @import if possible 
We really only need this stylesheet when we're resolving imported
cross-module @extends, which doesn't come up very often.

c794abd858 Eagerly dash-normalize Sass identifiers 
This avoids using maps and sets with custom equality, which are
moderately inefficient relative to built-in maps and sets on both Node
and the Dart VM. In order to make error messages continue to use the
original identifiers where possible, this updates some of them to rely
more heavily on their associated source spans for context.

7f2055e775 Make colorsByName a normal map 
There was no reason for this to be a normalized map, since color names
don't contain dashes or underscores.

58e9e74b37 Use list comprehensions in *Evaluate._evaluateArguments 
As well as being arguably more readable, the toList() method was
running a type check that was showing up as a minor bottleneck in JS
profiles.

a8e99e9152 Pass a dummy isValidKey callback to normalized map and set 
The default implementation runs a type check, which was a performance
bottleneck when compiled to JS. There's no need for this type check in
practice, since we never pass a non-String value to the contains(),
containsKey(), or remove() methods (and if we do, it will throw a
TypeError in our tests).

Support dart-lang/source_span#25 (#566) 
This adds a --no-unicode option to disable Unicode span rendering,
decouples repl highlighting from SourceSpan.highlight, and updates
tests to work with the new error highlighting.

It also tightly scopes source spans for statements with children.
Previously, source spans for these nodes extended all the way through
any whitespace that followed the node. This led to messy-looking
multiline span highlights with dart-lang/source_span#25.

Now, StylesheetParser.children doesn't consume trailing whitespace.
Instead, we add a helper method StylesheetParser._withChildren that
parses children, creates the appropriate span, and then consumes the
trailing whitespace.

Fix a performance bug in BinaryOperatorExpression.span (#569) 
Previously, evaluator called BinaryOperationExpression.span for each
binary operation it evaluated, which in turn called spanForList() to
create a span covering both child expressions. spanForList() then
called .span for both the left and right child operations *twice*,
leading to exponential behavior.

This is now avoided in three complementary ways:

1. The evaluator avoids eagerly calling AstNode.span, instead keeping
   the original AstNode until the span itself needs to be accessed.
   This means that a span will only be accessed when an error actually
   occurs, and then only one operation's span will be accessed.

2. BinaryOperationExpression.span now iterates through any child
   operations before calling their .span methods, so it only performs
   O(1) allocations.

3. spanForList() now only calls each AstNode.span once.

   have but did not until now.

2. It parses the component of a number after the decimal point using

a09a62538e Remove extra importer parameters from internal compile functions 
These can be passed as an ImportCache now, so they make the API more
confusing for relatively little benefit.

This also changes the const AsyncImportCache.none field to a non-const
AsyncImportCache.none() constructor. The const field didn't make sense
for a couple reasons: first, it wouldn't use a user's custom logger;
and second, it couldn't cache any relative imports, which were still
possible when the initial file was loaded from disk.

Add a ParenthesizedExpression class (#503) 
This allows us to accurately track the source spans for parenthesized
expressions, which in turn allows us to print accurate error
indications.

Adding a new class for this more accurately represents the structure
of the expression, but it also involves an extra allocation during
parsing and an extra level of nesting during evaluation which could
have a small but real performance impact.

We could alternatively add a package-internal setter for
Expression.span, and update the source span for parenthesized
expressions after they're initially parsed. However, this has its own
downsides: it adds complexity and mutability to the object model; and
many expression classes currently use lazily-generated spans, so
making them settable would require adding extra slots on those
classes.

I decided to go with the extra class because it only adds overhead
when parentheses are actually used in practice, as opposed to adding
overhead to every list/color/etc. The runtime overhead is also likely
to be mitigated if at any point we add a constant-folding step.

Fix an import-resolution bug (#488) 
When a stylesheet is imported, the parsed stylesheet object is cached
based on its canonical URL. However, the stylesheet.span.sourceUrl was
based on the text of the import that was used to load that stylesheet.
The idea was to make the source URL in stack traces look nicer, but it
meant that relative URLs could be resolved based on the old importer's
URL before being sent to the new importer, which caused bugs.

Now stylesheet.span.sourceUrl is always the canonical URL of the
stylesheet, and thus safe to cache. We then use the import cache to
convert the canonical URL to a human-friendly URL at the point at
which we generate stack traces.

This also deprecates support for relative canonical URLs. The
semantics of these URLs were always unclear, and with the new change
in import internals the old behavior doesn't make much sense. It's
preserved for backwards-compatibility, but deprecated.

Simplify trimming for extend (#460) 
We were previously trimming at bath the compound selector level and
the selector list level. This now only trims at the selector list
level.

The _trim() function also took a list of selector lists, on the
idea (from Ruby Sass) that it could avoid trimming selectors generated
from the same extension that were very unlikely to be redundant. In
practice, though, the fact that we weaved together selector lists at
the compound level meant that we didn't have meaningful
known-non-redundant lists like Ruby Sass did, so this wasn't useful.

This has no behavioral effect, although it does seem to improve
performance slightly for extend-heavy stylesheets.
