x86-64: Optimize load of all bits set into ZMM register [BZ #28252]

Optimize loads of all bits set into ZMM register in AVX512 SVML codes
by replacing

	vpbroadcastq .L_2il0floatpacket.16(%rip), %zmmX

and

	vmovups   .L_2il0floatpacket.13(%rip), %zmmX

with
	vpternlogd $0xff, %zmmX, %zmmX, %zmmX

This fixes BZ #28252.
