This cleans up and makes the tests easier to write and understand.
Also prepares for adding the WASM interpreter which needs a
different initialization sequence in tests.

I extended the Int64Lowering to lower calls, loads, stores, returns, and
parameters and apply the lowering on both the test function TF graph and
the WasmRunner TF graph.
The lowering of calls also requires an adjustment of the call descriptor.

The BufferedRawMachineAssemblerTester caused problems for the
Int64Lowering. Instead we construct a TF graph now which is compiled by
Pipeline::GenerateCodeForTesting.

The goal of the Int64Reducer is to replace all int64 nodes in a tf graph
with a set of int32 nodes such that 64 bit tf functions can be executed
on 32 bit platforms. At the moment the Int64Reducer only replaces
Int64Constants, TruncateInt64ToInt32, and Word64And.

Motivated by finding a bug in a larger module, this CL adds the ability
to dump out a byte-by-byte, nested view of the decoded AST. This
byte-by-byte output uses the opcode enum to make it readable, but is
suitable for pasting into a byte[] in C or JS and thus making a regression
test.
Also fix a bug; the case of running out of registers for indirect calls.
