Remove V64SFmode and V64SImode.

It's needed by avx5124vnniw/avx5124fmaps which have been removed by
r15-656-ge1a7e2c54d52d0.

gcc/ChangeLog:

	* config/i386/i386-modes.def: Remove VECTOR_MODES(FLOAT, 256)
	and VECTOR_MODE (INT, SI, 64).
	* config/i386/i386.cc (ix86_hard_regno_nregs): Remove related
	code for V64SF/V64SImode.
