    c++: conversion with trailing return type [PR101051]

    We've had a diagnostic for this, but since r10-6571 added an assert to
    splice_late_return_type, we need to diagnose before we call it.

            PR c++/101051

    gcc/cp/ChangeLog:

            * decl.c (grokdeclarator): Reject conversion with trailing return
            sooner.

    gcc/testsuite/ChangeLog:

            * g++.dg/cpp0x/trailing15.C: New test.
