Konstantin Shcheglov 39b71253ce Fix for curly_braces_in_flow_control_structures lint. 
Quick assist for converting single line statements to blocks and
vice-versa is also sometimes useful, but separate.

Paul Berry 51046368c5 Move NNBD migration tool to a fresh package. 
This gives us more flexibility for how we want to publish and deploy
the tool.  We now have the option, for example, of making a command
line app that invokes the tool and does not depend on analysis_server.

Note that some testing infrastructure had to be duplicated.  I plan to
consolidate this infrastructure in follow-up CLs.

Paul Berry e31af09992 Remove NullabilityMigrationAssumptions class. 
This was a lot of bookkeeping for very little added value.  If we want
to experiment with changing the behavior of the migration tool in the
future, we should experimentally change it and see whether the quality
of the migration improves; it's not worth speculatively keeping
multiple behaviors around while the tool is being developed.

Paul Berry 709df79404 Clean up logic to decide whether to create hard edges 
Previously we were creating hard edges for the default values of
optional parameters.  This was incorrect; we don't want a hard edge
because we don't want evidence of non-nullability to propagate
upstream from an optional parameter to the const expression that sets
its default value.

Paul Berry 01694dcca1 Handle nullability nodes for dynamic types more cleanly. 
Rather than use an edge from `always` to ensure that these nodes are
nullable (which is error prone since it could be overridden by an
assertion), we simply place these nodes in the ordinary nullable state
at the time they are created.

As a side effect we can reduce the amount of code we have to plumb the
nullability graph through.

Paul Berry b8050f9322 Make NullabilityNode.nullable private. 
This will help ensure that we don't accidentally make more use of it
before removing the constraint variable migration implementation
entirely.

Paul Berry d47c31da48 Remove NullabilityNode.isNeverNullable. 
This method relied on querying the underlying constraint variable, so
it needed to go in order to migrate away from the contraint variable
implementation.

Paul Berry df7db795dc Stop using ConstraintVariable.always to represent the nullability of dynamic. 
This is a necessary part of reworking nullability migration to stop
using constraint variables entirely.

Paul Berry d06c7b7c89 Remove the ability of migration to use ?s in input files as a hint. 
This speculative feature turned out to be infeasible, since the files
that are input to migration have NNBD disabled, so `?` is not
permitted.

Paul Berry 2c3114f7a7 Replace most uses of assertConstraint with assertConnection. 
This helps reduce the use of constraint variables in nullability
migration tests.
