S/390: Get rid of Y constraint in vector.md.
This finally removes the Y constraint from the vector patterns while
folding some of them using a code iterator.
gcc/ChangeLog:
2016-03-01 Andreas Krebbel <krebbel@linux.vnet.ibm.com>
* config/s390/subst.md (DSI_VI): New mode iterator.
("addr_style_op_subst"): Use DSI_VI instead of DSI.
* config/s390/vector.md ("vec_set<mode>"): Move expander before
the insn definition.
("*vec_set<mode>"): Change predicate and add alternative to
support only either register or const_int operands as element
selector.
("*vec_set<mode>_plus"): New pattern to support reg + const_int
operands.
("vec_extract<mode>"): New expander.
("*vec_extract<mode>"): New insn definition supporting reg and
const_int element selectors.
("*vec_extract<mode>_plus"): New insn definition supporting
reg+const_int element selectors.
("rotl<mode>3", "ashl<mode>3", "ashr<mode>3"): Merge into the
following expander+insn definition.
("<vec_shifts_name><mode>3"): New expander.
("*<vec_shifts_name><mode>3<addr_style_op>"): New insn definition.
