middle-end/106053 - fold_sign_changed_comparison and large bools
The following fixes a latent issue in the match.pd variant of
fold_sign_changed_comparison which replaces an unsigned integer
comparison with a signed boolean comparison of the same precision
despite the fact that we treat BOOLEAN_TYPEs as only having two
valid values.

* match.pd ((T)a == (T)b): Avoid folding away sign
changes in a comparison if we'd truncate to a boolean.
* gcc.target/i386/pr106053.c: New testcase.
