PR tree-optimization/91091
* tree-ssa-sccvn.c (vn_reference_lookup_3): Use correct
alias-sets both for recording VN table entries and continuing
walking after translating through copies. Handle same-sized
reads from SSA names by returning the plain SSA name.
(eliminate_dom_walker::eliminate_stmt): Properly handle
non-size precision stores in redundant store elimination.
* gcc.dg/torture/20191011-1.c: New testcase.
* gcc.dg/tree-ssa/ssa-fre-82.c: Likewise.
* gcc.dg/tree-ssa/ssa-fre-83.c: Likewise.
* gcc.dg/tree-ssa/redundant-assign-zero-1.c: Disable FRE.
* gcc.dg/tree-ssa/redundant-assign-zero-2.c: Likewise.
