Restores some sensemaking properties, such as making src/machine-type.h (lower level header) independent of src/zone/zone.h (higher level header).

Fix two issues in the interpreter entry for 64 bit return values on 32 bit platforms. First, the effect chain was slightly incorrect, second the order of the returned values was wrong. Also add a test case for this. Tested on x64, ia32 and s390. Plus drive-by fix in Int64Lowering to reuse global constants for big-endian/little-endian disambiguation.

The int64-lowering only lowered store instructions with a word64 store representation. For all other stores the default lowering applied. The default lowering replaces all input nodes with both their replacement nodes, which can change the number of input nodes of the lowered node. In WebAssembly there exist stores which take an I64 input and store it with a different representation, e.g. I32. In TurboFan this translates to a store node with word32 store representation and a word64 value input. The default lowering replaces the word64 value input to become two word32 value inputs, which makes the number of inputs of the store node invalid. This CL discards the high word replacement of the value input so that the number of input nodes of a store node does not change in the default lowering.

This is some initial cleanup to keep /src clean. The AccountingAllocator is actually exclusively used by zones and this common subfolder makes that more clear. BUG=v8:5409 Review-Url: https://codereview.chromium.org/2344143003 Cr-Commit-Position: refs/heads/master@{#39558}

Int64Mul is lowered to a new turbofan operator, Int32MulPair. The new operator takes 4 inputs an generates 2 outputs. The inputs are the low word of the left input, high word of the left input, the low word of the right input, and high word of the right input. The ouputs are the low and high word of the result of the multiplication.

The new implementation deals with cycles in the TF graph in two steps: 1) The lowering of phis is delayed to avoid cyclic dependencies. 2) The replacement nodes of phis are created already when the phi is pushed onto the stack so that other nodes can use these replacements for their lowering.

On 32-bit systems FXXXConvertI64 instructions are compiled to calls to C functions. The TF node for the function call is already generated in the wasm compiler, the lowering of the I64 parameter is done in the Int64Lowering.

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. R=titzer@chromium.org Review URL: https://codereview.chromium.org/1704033002 Cr-Commit-Position: refs/heads/master@{#34121}

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.
