    attribs: Restrict decl_attributes DECL_FUNCTION_SPECIFIC_TARGET changes to
targets that care about target attributes/pragmas [PR105234]

    The following code is rejected e.g. on mips64el-linux (but I think many
    other targets which don't support target attribute or pragma).
    The problem is that the change to decl_attributes below is done
    unconditionally and with just #pragma GCC push_options/pop_options pair
    we have target_option_default_node NULL, but after popping options
    target_option_current_node becomes non-NULL and this decl_attribute
    spot fills in DECL_FUNCTION_SPECIFIC_TARGET of a subset of a functions.
    Those appearing before push_options/pop_options will have it NULL and
    as target_option_default_node is also NULL on those targets, the default
    can_inline_p will refuse to inline any functions defined with NULL
    DECL_FUNCTION_SPECIFIC_TARGET into any function with non-NULL
    DECL_FUNCTION_SPECIFIC_TARGET (even when nothing in the options really
    changed).

    The following patch restricts that snippet to targets that care (initialize
    target_option_default_node to non-NULL to the command line options early)
    which include all targets that actually implement target attribute and/or
    pragma.
