S/390: Don't use vgm for v1ti and v1tf.
gcc/ChangeLog:
2015-09-10 Andreas Krebbel <krebbel@linux.vnet.ibm.com>
* config/s390/s390.c (s390_contiguous_bitmask_vector_p): Reject if
the vector element is bigger than 64 bit.
gcc/testsuite/ChangeLog:
2015-09-10 Andreas Krebbel <krebbel@linux.vnet.ibm.com>
* gcc.target/s390/vector/vec-genbytemask-1.c: Add check for V1TI
initialization with a byte mask. No change expected here.
* gcc.target/s390/vector/vec-genmask-1.c: Fix whitespace.
* gcc.target/s390/vector/vec-genmask-2.c: Add check for V1TI
initialization with contigious bitmask. Literal pool is expectd
to be used here.
