Also adds `firstOrNull`, `lastOrNull`, `singleOrNull`, and `elementAtOrNull`.
I chose `nonNulls` instead of `whereNotNull()`.
The latter should have been a getter, but isn't.
Making it a getter in the platform libraries would be confusing,
and make migrating from `package:collection`'s function harder,
so instead I gave it a completely new name.
The alternative would be to retain the non-idiomatic `whereNotNull()`
for familiarity. But then it would be tool late to fix.

On the web, some inputs to `Duration` would make -0.0
occur in positions where the code assumed an integer
with a reasonable `toString`.
Adds `+ 0` and using `0 - x` instead of `-x` to
avoid ever ending up with a `-0.0`.

Mark tests that contain errors about using a class as a mixin to use
language version 2.19 where that's not an error.
This may not fix all of the tests because it's the language version of
the library where the class is declared that matters, not where the
class is used as a mixin. But most tests have all of their declarations
in the same library, so this should fix most.

The test stacktrace_current compares two stack traces by masking any
line numbers.
With dart2wasm, V8 shows function offsets instead of line numbers, in
hex, which causes the test to fail with unrelated changes.
This updates the regex to mask hex numbers as well, making the test
stable with unrelated dart2wasm changes.

Apparently the web implementation of RegExp has drifted from the native implementation in a very subtle way. To prevent further drift, this CL refactors named-captures_test into two tests, one which fails on all web backends currently(named_captures_2_test), and one that passes on all backends(named-captures_test, named unchanged to preserve history).

When using `Uri.parse` or `Uri(path:..)`, a `\` is treated as, and converted to, a `/`.
This avoids a particular problematic difference in behavior between Dart and the browser's `URL` functionality. There are still examples where the two differ in interpretation of the same code, but in those cases, the Dart `Uri` will most likely end up without a host name, which should be easily detected.

Compilers named "dartdevc" and "dartdevk" should be listed together
at all locations. These are now aliases for the same compiler
across different configurations.
In the future these names should converge on "dartdevc".
Some skipped tests for "dartdevc" no longer need to be skipped but
currently there are no configurations are running those tests with
that compiler name so removing the skips shows no change in test
results.

Correctness changes:
Fix SEGV by checking for overflow in computing the length of the
repeated string.
Performance changes:
Use unnested loops to fill the string instead of nested loops.
Implement `operator *` for _TwoByteString in the same way.
(The default implementation using StringBuffer causes a lot of
allocations. For example, `"α" * 10000` repeatedly adds the small
string to the StringBuffer, which repeatedly compresses a sequence of
small strings to make a bigger string to stop the list of parts
becoming too large. This compression creates a lot of small strings
with the same contents.)

The `toString` used the sign of `hours` to get a leading `-`
when the duration is negative. However, a negative duration of
less than one hour would therefore miss out on the sign,
because `-0` is not an integer.
Now handles sign explicitly.
Fixes#48841.
