Convert Ir Into X64 (X86_64)

## Limitations

#### No Segmentation Registers

#### No X87 Support

#### No access to the upper 8 bits of the lower 16 bits of registers AX, BX, CX, DX

## Required Implicit Registers

Instructions that implicitly modify a register now require the register as an operation

# Operation

Each instruction is written with varardic c functions with `TYPE`, `DATA` syntax

## TYPE

### General Registers Width

### General Register Addresses Width

### General Register Scale

### General Register Id

### General Register Memory Displacement

### XMM Registers

### MM Registers

### Immediate Value

### Relative Address

### Label

## DATA

## Object Definitions

```c
kpl_x64_lable(label)

kpl_x64_inst(INSTRUCTION, [TYPE, VALUE]..., END)

kpl_x64_inst_pfx(PREFIX, INSTRUCTION, [TYPE, VALUE]..., END)
```
