Introduce HPrimitiveCheck for checking the receiver or argument of
primitive operations. These will eventually go away with NNBD since it
will be a call-site type error to invoke `+` with a null receiver or
operand.

This preserves the invariant that method invocations and property sets
with an interface target handle static types at the call site.
This is a prerequisite to improving dart2js with implicit checks.
With this we can mark dynamic invocations a statically safe and
discover when instance methods don't need to check parameter types.

This uses the information from the static types now used in inference which
can improve the precision in particular for generic classes. Since type
masks lose the type argument information, we cannot expect locating members
based on the type mask to be more precise than what has been found through
the static types.
This CL also expands the unit test framework to support unit test of
optimizations and the emission model, including tests of the improved
field access handling.
