tree-optimization/116406 - ICE with int<->float punning prevention
The following does away with the idea to use non-symmetrical
testing of mode_can_transfer_bits in hash-table equality testing.
It isn't feasible to always control query order to maintain
consistency.
PR tree-optimization/116406
* tree-ssa-sccvn.cc (vn_reference_eq): Never equate
float and int when the float mode cannot transfer bits.
Do not try to anticipate which is the mode we actually load
from.
* gcc.dg/tree-ssa/pr116406.c: New testcase.
* gcc.dg/tree-ssa/ssa-pre-30.c: On x86 dd -msse -mfpmath=sse.
