Implement int-to-double literal conversion.

The implementation strategy is to replace int literals with double
literals during type inference, provided they occur in a double
context and can be represented exactly as a double.  This requires us
to keep integer literals larger than the 64-bit range until after type
inference and to keep the source text of 64-bit integers until after
type inference for error reporting.

We postpone the check for web int literals as well because the
expression generator that was performing it isn't otherwise needed.

Fixes https://github.com/dart-lang/sdk/issues/34357.
