    Fix pr115388.c: plain char could be unsigned by default [PR115415]

    This is a simple fix to the testcase as plain `char` could be
    unsigned by default on some targets (e.g. aarch64 and powerpc).

    Committed as obvious after quick test of the testcase on both aarch64 a=
nd
x86_64.

            PR tree-optimization/115388
            * gcc.dg/torture/pr115388.c: Use `signed char` directly instead
            of plain `char`.
