This change substitutes the string based emission mechanism with
cranelift-codegen's x64 backend.
This change _does not_:
* Introduce new functionality in terms of supported instructions.
* Change the semantics of the assembler/macroassembler in terms of the logic to
emit instructions.
The most notable differences between this change and the previous version are:
* Handling of shared flags and ISA-specific flags, which for now are left with
the default value.
* Simplification of instruction emission per operand size: previously the
assembler defined different methods depending on the operand size (e.g. `mov`
for 64 bits, and `movl` for 32 bits). This change updates such approach so that
each assembler method takes an operand size as a parameter, reducing duplication
and making the code more concise and easier to integrate with the x64's `Inst` enum.
* Introduction of a disassembler for testing purposes.
As of this change, Winch generates the following code for the following test
programs:
```wat
(module
(export "main" (func $main))
(func $main (result i32)
(i32.const 10)
(i32.const 20)
i32.add
))
```
```asm
0: 55 push rbp
1: 48 89 e5 mov rbp, rsp
4: b8 0a 00 00 00 mov eax, 0xa
9: 83 c0 14 add eax, 0x14
c: 5d pop rbp
d: c3 ret
```
```wat

(func $main (result i32)

(i32.const 20)
(local.set $bar)
(local.get $foo)
(local.get $bar)
i32.add
))
```
```asm
