MachineType now tracks both the representation and the value type of machine quantities and is used uniformly throughout TurboFan.

These types can now express uint8, int8, uint16, and int16, i.e. signed and unsigned smallish integers. Note that currently only uint8 and uint16 are implemented in the TF backends.

As discussed in person with Benedikt, it is better to remove the assertion because it is too brittle. The assertion says that the continuation block should immediately follow the call. However, there are exceptions - such as nop or constant pool in-between being fine - that make the assertion brittle.
