[turbofan] Add proper conversion operators for int32<->int64.
...
This affects arm64 and x64. Note that we do not yet optimize
these conversions. Later we will add support for merging these
conversion operators into other operations during instruction
selection.

Revert "[arm] Shorter test names for parameterized tests."
...
This reverts commit r23142 because GoogleTest is very picky about the
parameterized test case names, so not even using an anonymous namespace
can please GTest. Also reverts the renaming applied to in the
ChangeLowering unit test.

[turbofan] Add new ControlEffect and Finish operators.
...
Fix the ChangeLowering to properly use ControlEffect nodes
to turn the control output of IfTrue nodes into an effect
input for the Load nodes, and to properly use Finish nodes
to ensure that allocation and store were both performed
prior to actually using the allocated heap number.

Unify MachineType and RepType.
...
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.
