    Use numeric local labels to allow compilation with LTO enabled
    
    Some assembly snippets in instructions_testcode.c used regular label
    names.  Unfortunately, when multiple copies of the snippets are
    inlined in different places with LTO enabled the multiple copies of a
    label by the same name cause the build to fail because of the
    redefinition of the label.  To avoid this problem all those labels
    have been converted to numeric local labels to allow multiple copies
    to peacefully coexist in the LTO enabled code.
