Ok with a proper
Ok, reworked version. The folding of X op X and !X op !X seems indeed
not being necessary. So function simplifies much.
Bootstrapped and regression tested for all standard languages (plus
Ada and Obj-C++). Ok for apply?

Hello,
this patch implements the X op !X patterns within tree-ssa-forwprop.c without
using here const-fold routines. Additionally it does some trivial folding for
X op X. Implementation
also looks through [(type)] X op [(type)] !X, if type of X is integral and
precision is suitable
