[Bug c/71522] Wrong optimization of memcpy through a var of type long double

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=71522 --- Comment #1 from Alexander Cherepanov --- This is run on x86-64, sizeof(long double) == 16. The string literal is 15 letters 'A' and a terminating 0. To get the same effect on x86-32 the string should be shortened by four 'A'.
