    i386: Obfuscate avx10_2bf16intrin.h inline function arguments [PR123155]

    Function arguments in installed headers need to be obfuscated (unlike
    object-like macro arguments), as e.g.
    is a valid program.  Most of the arguments are obfuscated, but some
    leaked in in the avx10_2bf16intrin.h header.
