re PR middle-end/88963 (gcc generates terrible code for vectors of 64+ length which are not natively supported)

PR tree-optimization/88963
* tree-ssa-forwprop.c (pass_forwprop::execute): Rewrite
vector loads feeding only BIT_FIELD_REFs to component
loads. Rewrite stores fed by CONSTRUCTORs to component
stores.
* gcc.dg/tree-ssa/ssa-fre-31.c: Disable forwprop.
* gcc.target/i386/pr88963-1.c: New testcase.
* gcc.target/i386/pr88963-2.c: Likewise.
