0x4ef6030 width_2(D) 1 times vec_construct costs 32 in prologue
0x4ef6030 width_2(D) 1 times vector_store costs 24 in body
0x4f59760 width_2(D) 1 times scalar_store costs 12 in body
0x4f59760 height_4(D) 1 times scalar_store costs 12 in body

0x4f59760 y_8(D) 1 times scalar_store costs 12 in body
t2.c:18:3: note: Cost model analysis:
Vector inside of basic block cost: 24
Vector prologue cost: 32
Vector epilogue cost: 0
Scalar cost of basic block: 48
t2.c:18:3: missed: not vectorized: vectorization is not profitable.
t2.c:18:3: note: ***** Re-trying analysis with vector size 16
so target costs say that this isnt profitable. Probably a dup of one of the
bugs saying we don't take into account function boundary ABI for costing.
