    rs6000: Fix ASAN linker errors for Power ELF V1 ABI [PR113284]

    rs6000_elf_declare_function_name () outputs Power ELF V1 ABI function
    entry labels without using ASM_OUTPUT_FUNCTION_LABEL ().  As a result,
    .LASANPC labels are not emitted, causing linker errors.

    In theory, it is possible to reuse ASM_OUTPUT_FUNCTION_LABEL () by
    changing rs6000_output_function_entry () to generate label names
    without outputting them, but this would be quite a large change.

    Instead, factor out the .LASANPC emitting code from
    ASM_OUTPUT_FUNCTION_LABEL () and call it manually.

    Fixes: c659dd8bfb55 ("Implement ASM_DECLARE_FUNCTION_NAME using
ASM_OUTPUT_FUNCTION_LABEL")
