    gimple-lim: Reuse boolean var when moving PHI

    While looking into PR 117859, I noticed that LIM
    sometimes would produce `bool_var2 = bool_var1 != 0` instead
    of just using bool_var2. This patch allows LIM to reuse bool_var1
    in the place where bool_var2 was going to be used.

    Bootstrapped and tested on x86_64-linux-gnu.

    gcc/ChangeLog:

            * tree-ssa-loop-im.cc (move_computations_worker): While moving
            phi, reuse the lhs of the conditional if it is a boolean type.
