[c-family] Small fix for -fdump-ada-spec

[Eric Botcazou via Gcc-patches]

This is needed to support the _Float32 and _Float64 types.

Tested on x86-64/Linux, applied on the mainline.

        * c-ada-spec.cc (is_float32): New function.
        (is_float64): Likewise.
        (is_float128): Tweak.
        (dump_ada_node) <REAL_TYPE>: Call them to recognize more types.
