    OpenMP: Use VOID_TYPE_P to check for void return type in SIMD function
clones.

    This change fixes an issue where functions
    decorated with:
    pragma omp declare simd
    that return void via a typedef would crash
    GCC with an ICE while compiling a program
    containing such a function, by using
    VOID_TYPE_P instead of directly comparing
    to void_type_node. New testcase added.

    gcc/ChangeLog:

            * omp-simd-clone.cc (simd_clone_adjust_return_type): Use
VOID_TYPE_P
            when checking for void return type in adjusted functions.
            (simd_clone_adjust): Likewise.

    gcc/testsuite/ChangeLog:

            * gcc.dg/gomp/pr111856.c: New test.
