Detailed description

This PR adds support for the Infineon C166 microcontroller architecture. The implementation includes:

1. Architecture plugin definition (arch_c166.c)
2. Assembly/disassembly support (asm_c166.c)
3. Analysis plugin for C166 instructions (analysis_c166.c)
4. Core disassembler implementation (c166_disas.c and c166_disas.h)
5. Comprehensive opcode definitions and addressing modes (c166_ops.h)

Key features of this implementation:

• Support for basic arithmetic, logical, and bit manipulation operations
• Control flow analysis for jumps, branches, and function calls
• Proper handling of different C166 addressing modes
• Register profile definition for the C166 architecture

The code has been manually tested with a set of test binaries covering the main instruction categories.

Test plan

The implementation has been tested with several binary files containing different types of C166 instructions:

1. Arithmetic operations (ADD, ADDC, SUB, MUL, etc.)
2. Logical operations (AND, OR, XOR, etc.)
3. Control flow operations (JMPR, JB, etc.)
4. Data movement operations (MOV, MOVB, etc.)
5. Bit manipulation operations (BCLR, BSET, etc.)

Test commands used:

Arithmetic operations test

echo -ne "\x00\x12\x06\x01\x23\x45\x10\x34\x20\x56\x30\x78\x0B\x12" > c166_arithmetic.bin

Logical operations test

echo -ne "\x60\x12\x66\x01\x23\x45\x70\x34\x50\x56\x91\x01" > c166_logical.bin

Jump and branch operations test

echo -ne "\x0D\x05\x2D\xFC\x3D\x10\x8A\x20\x10\x05\x8D\x0A" > c166_branch.bin

Data movement operations test

echo -ne "\x88\x12\x89\x34\x84\x05\x20\x00" > c166_movement.bin

Bit operations test

echo -ne "\x0E\x20\x0F\x21\x2E\x22\x2F\x23" > c166_bit.bin

Combined operations test

echo -ne "\x00\x12\x60\x34\x88\x56\x0D\x08\x0B\x78\x20\x56\x0F\x24\x40\x12\x2D\xFA" > c166_combined.bin
