[DirectX] Implement Shader Flag Analysis for `TiledResources`

[bharadwajy]

Set the function-level flag, if

• DXIL::Opcode::CheckAccessFullyMapped is used OR
• either of DXIL::Opcode::SampleCmpClamp or DXIL::Opcode::SampleCmpBias is used with non-zero clamp in its last argument.

This is named m_bTiledResources in DXC. See here for reference.

AC:

Add tests to verify correctness of analysis.

Note: description needs updating as there isn't actually an opcode called SampleCmpClamp. It seems that this is just referring to an argument to SampleCmd.
