    Fix fold-vec-splat-floatdouble testsuite failure on power10
    
    When I added support for generating XXSPLTIDP on December 15th, 2021, I
    missed updating the fold-vec-splat-floatdouble.c test to add to the regex
    for the instructions generated.  This patch fixes that.

            * gcc.target/powerpc/fold-vec-splat-floatdouble.c: Fix insn regex
            on power10.
