S/390: movdf improvements
This patch add the vector load element from immediate instruction to the
movdf/dd pattern for loading a FP zero and it removes the vector
instructions from the mov<mode>_64 pattern. These were pointless in
there because z13 support implies DFP support so these instructions will
always be matched in the mov<mode>_64dfp pattern instead.
Regression tested on s390x
gcc/ChangeLog:
2017-03-24 Andreas Krebbel <krebbel@linux.vnet.ibm.com>
* config/s390/s390.md ("mov<mode>_64dfp" DD_DF): Use vleig for loading a
FP zero.
("*mov<mode>_64" DD_DF): Remove the vector instructions. These
will anyway by matched by mov<mode>_64dfp.
