Use function attributes for SSE 4.2 even when targeting that extension
On Red Hat 9 systems (or similar), the packaged gcc targets x86-64-v2,but clang does not. This has caused build failures in the wake ofcommite2809e3 when building --with-llvm.The most expedient fix is to use the same function attributes forthe inlined function as we do for the global function.Reported-by: Kyotaro Horiguchi <horikyota.ntt@gmail.com> (plus members skimmer and bumblebee)Diagnosed-by: Tom Lane <tgl@sss.pgh.pa.us>Tested-by: Todd Cook <cookt@blackduck.com>Discussion:https://postgr.es/m/CANWCAZZSxs3a1YRKehkgk2OHKbrVn+xZ+AWW8Co2R_f70NqqmA@mail.gmail.com
