adjust gcc.dg/cpp/ucs.c

[Richard Henderson <rth at redhat dot com>]

This has been failing on Alpha since it was added.  I finally got
around to looking at it.

On x86, HOST_WIDE_INT is normally 32 bits wide, as is wchar_t, so
the number of wide characters we can represent is one, thus the
expected "character constant too long" warning.

On Alpha, HOST_WIDE_INT is normally 64 bits wide, but wchar_t is
32 bits wide, thus we can represent a wide multi-character constant
with two elements, and we fall into the "multi-character character
constant" warning.

I.e. everything's kosher after all (unless you want to take the
stance that we should have suppressed the additional warnings after
cpp_parse_escape fails, which I don't since that's more work).
