  [AsmPrinter] Do not emit label instructions after the function body if the target is SPIR-V (#107013)

AsmPrinter always creates a symbol for the end of function if valid
debug info is present. However, this breaks SPIR-V target's output,
because SPIR-V specification allows label instructions only inside a
block, not after the function body (see
https://registry.khronos.org/SPIR-V/specs/unified1/SPIRV.html#OpLabel).
This PR proposes to disable emission of label instructions after the
function body if the target is SPIR-V.

This PR is a fix of the
https://github.com/llvm/llvm-project/issues/102732 issue.
