re PR rtl-optimization/84101 (-O3 and -ftree-vectorize trying too hard for function returning trivial pair-of-uint64_t-structure)

PR tree-optimization/84101
* tree-vect-stmts.c: Include explow.h for hard_function_value,
regs.h for hard_regno_nregs.
(cfun_returns): New helper.
(vect_model_store_cost): When vectorizing a store to a decl

account for the possible spilling that will happen.
* gcc.target/i386/pr84101.c: New testcase.
