[CIR] naked asm not supported

Leaving a tracking issue for naked asm in clang IR. The code currently has an NYI when trying to compile a naked asm function:

https://github.com/llvm/llvm-project/blame/main/clang/lib/CIR/CodeGen/CIRGenFunction.cpp#L440

Start at clang/lib/CIR/CodeGen/CIRGenFunction.cpp around line 440, where the issue reports the NYI for naked asm functions. Reproduce compilation of a naked asm function, trace the CIR code-generation path, and verify that the function compiles without reaching the NYI; the issue does not name a test file.
