c-family: ICE with [[gnu::nocf_check]] [PR106937]
When getting the name of an attribute, we ought to use
get_attribute_name, which handles both [[]] and __attribute__(())
forms. Failure to do so may result in an ICE, like here.
pp_c_attributes_display wasn't able to print the [[]] form of
attributes, so this patch teaches it to.
When printing a pointer to function with a standard attribute, the attribute
should be printed after the parameter-list. With this patch we print:
aka 'void (*)(int) [[gnu::nocf_check]]'
or, in C++ with noexcept:
aka 'void (*)(int) noexcept [[gnu::nocf_check]]'
pp_c_attributes has been unused since its introduction in r56273 so
this patch removes it.
