Use TImode for piecewise move in 64-bit mode
Use TImode for piecewise move in 64-bit mode. We should use TImode in
32-bit mode and use OImode or XImode if they are available. But since
by_pieces_ninsns determines the widest mode with MAX_FIXED_MODE_SIZE,
we can only use TImode in 64-bit mode.

* config/i386/i386.h (MOVE_MAX_PIECES): Use TImode in 64-bit
mode if unaligned SSE load and store are optimal.
