The ld.so diagnostics already prints AT_HWCAP values, but only in hexadecimal. To avoid duplicating the strings, consolidate the hwcap_names from cpu-features.h on a new file, dl-hwcap-info.h (and it also improves the hwcap string description with more values). For future AT_HWCAP3/AT_HWCAP4 extensions, it is just a matter to add them on dl-hwcap-info.c so both ld diagnostics and tunable filtering will parse the new values. Checked on powerpc64le-linux-gnu.
