re PR tree-optimization/88739 (Big-endian union bug)

2019-01-28  Richard Biener  <rguenther@suse.de>

PR tree-optimization/88739
* tree-cfg.c (verify_types_in_gimple_reference): Verify
BIT_FIELD_REFs only are applied to mode-precision operands
when they are integral.
(verify_gimple_assign_ternary): Likewise for BIT_INSERT_EXPR.
* tree-ssa-sccvn.c (vn_reference_lookup_3): Avoid generating
BIT_FIELD_REFs of non-mode-precision integral operands.
