A truncated version of char32_literal_test.c++

I also made another program that tests ALL possible char32_t literals and
demonstrates that U+0000 (Null) is the only one that fails on gcc (it works on
clang).

The attached program is truncated because the full program is over 17 MiB, but
the literals were just generated with a script like this (surrogates were just
cut out by hand with vim):

for i in {0..1114111}; do printf "\tU'\\\\U%08x',\n" $i; done >
char32_literal_test.c++
