libstdc++: Fix reading UTF-8 characters for 16-bit targets [PR104875]
The current code in read_utf8_code_point assumes that integer promotion
will create a 32-bit int, but that's not true for 16-bit targets like
msp430 and avr. This changes the intermediate variables used for each
octet from unsigned char to char32_t, so that (c << N) works correctly
when N > 8.
libstdc++-v3/ChangeLog:
PR libstdc++/104875
* src/c++11/codecvt.cc (read_utf8_code_point): Use char32_t to
hold octets that will be left-shifted.
