amdgcn: add more insn patterns using vec_duplicate
These new insns allow more efficient use of scalar inputs to 64-bit vector
add and mul. Also, the patch adjusts the existing mul.._dup because it was
actually a dup2 (the vec_duplicate is on the second input), and that was
inconveniently inconsistent.
The patterns are generally useful, but will be used directly by a follow-up
patch.
gcc/ChangeLog:
* config/gcn/gcn-valu.md (add<mode>3_dup): New.
(add<mode>3_dup_exec): New.
(<su>mul<mode>3_highpart_dup<exec>): New.
(mul<mode>3_dup): Move the vec_duplicate to operand 1.
(mul<mode>3_dup_exec): New.
(vec_series<mode>): Adjust call to gen_mul<mode>3_dup.
* config/gcn/gcn.cc (gcn_expand_vector_init): Likewise.
(cherry picked from commit bdc4062a0796788e44d5e6ecd753268a8b453cc7)
