Web platforms do not support dart:isolate--`dartdevc` already treats it
as false, but this fix is needed if using `--kernel` and conditional
imports (which are handled by the front_end rather than dev_compiler).

This change extends/fixes the exiting "pattern recognition" which tries
to recognize the pattern
v2 <- LoadClassIdInstr(v1)
BranchIf v2 == IntegerConstant(cid)
Furthermore we start inlining the recognized `ClassID.getID` method very
early in the pipeline. This allows the VM to recognize the above
pattern and insert redefinitions before the actual inlining pass.
Furthermore we special-case two very hot methods in utf8 decoding by
manually having two loops, one of which is guarded by a class-id check
against the _Uint8ArrayView class, which is most common. (In the future
we would like to unify the typed data layouts so we no longer need to
use `ClassId.getID`, thereby also allowing non core library code to use
this).

In Dart 2.0 types are enforced at signature boundaries, so most of the
type checks on arguments are serving no other purpose other than
disalllowing `null`. Make that explicit in these checks.
Unnecessary checks were discovered by searching for "if (\w+ is" and
filtering down to the checks that match exactly against a type argument.
Checks in any files related to "js" or "dart2js" are left alone.
In a few places there will be a user visible behavior change where
ArgumentErrors will reference "not null" instead of "not a String" etc.
Client code should not be relying on these details and the new messages
should be more clear.
Updated checks take a few forms:
- ArgumentError.checkNotNull
- Changing `value is SomeType` to `value != null` where it's combined
with other conditions.
- Where non-null values are already guaranteed or allowed, drop the
check.
Other changes:
- Use single line short circuit returns or throws where possible.
- In some places change an ArgumentError to a RangeError for
consistency.
- Some minor formatting changes with the latest dartfmt.

The current DateTime class takes DateTime objects as arguments,

That does not work if someone else implements the DateTime interface.

mDNS queries (and many other local queries) should be allowed to set
their TTL to 255. This patch enables that on all platforms.
On macOS in particular, a system service reserves the mDNS port. The
socket option SO_REUSEPORT is required in addition to SO_REUSEADDR to
successfully bind there; the flag is also supported on Linux, so this
patch allows it to be used there as well (but prints an error message if
it's used on any other platform).
I could use some guidance as to tests for this - is it support availble
for running tests only on specific platforms?
