Simplify code expressions

Strive for clarity by simplifying code expressions and reducing unnecessary complexity. Complex or verbose expressions decrease readability and increase the chance of errors during maintenance.

Key simplification practices:

1. Simplify verbose expressions - Use the most direct syntax possible: ```cpp // Overly verbose: PrecodeMachineDescriptor::Init(&(&g_cdacPlatformMetadata)->precode);

// Simplified: PrecodeMachineDescriptor::Init(&g_cdacPlatformMetadata.precode);

2. **Use appropriate types** - Prefer language-native types for internal details:
```cpp
// Less appropriate for internal usage:
Volatile<BOOL> g_GCBridgeActive = FALSE;

// Better:
Volatile<bool> g_GCBridgeActive = false;

1. Reduce nesting - Flatten nested conditions and blocks when possible: ```cpp // Highly nested and harder to follow: if (g_interpModule != NULL) { if (methodInfo->scope == g_interpModule) doInterpret = true; else doInterpret = false; }

// Flattened and clearer: bool doInterpret = false; if ((g_interpModule != NULL) && (methodInfo->scope == g_interpModule)) doInterpret = true;

4. **Use parentheses in logical expressions** per coding guidelines:
```cpp
// Incorrect:
if (ins == INS_rcl_N || ins == INS_rcr_N || ins == INS_rol_N || ins == INS_ror_N)

// Correct:
if ((ins == INS_rcl_N) || (ins == INS_rcr_N) || (ins == INS_rol_N) || (ins == INS_ror_N))

1. Extract helper methods for repeated patterns: ```cpp // Repeated pattern: if (attr == EA_4BYTE) { GetEmitter()->emitIns_R_R_I(INS_addiw, attr, retReg, op1->GetRegNum(), 0); } else { GetEmitter()->emitIns_R_R(INS_mov, attr, retReg, op1->GetRegNum()); }

// Extract to helper: emitMoveIfZeroImmediate(retReg, op1->GetRegNum(), attr);

6. **Collapse related conditionals** into helper functions:
```cpp
// Verbose:
if (IsAVXVNNIInstruction(ins) || IsAVXVNNIINT8Instruction(ins) || IsAVXVNNIINT16Instruction(ins))

// Better:
if (IsAvxVnniFamilyInstruction(ins))

Simpler code is easier to read, test, and maintain.
