Support TImode CONST_WIDE_INT store in 64-bit STV

Support TImode CONST_WIDE_INT store generated from piecewise store.
Need to verify performance impact before enabling TImode CONST_INT
store for __int128.

gcc/

* config/i386/i386.c (timode_scalar_to_vector_candidate_p): Allow
TImode CONST_WIDE_INT store.
(timode_scalar_chain::convert_insn): Handle CONST_WIDE_INT store.

gcc/testsuite/

* gcc.target/i386/pieces-strcpy-1.c: New test.
* gcc.target/i386/pieces-strcpy-2.c: Likewise.
