PR modula2/118600 Assigning to a record causes alignment exception
This patch recursively tests every assignment (of a constructor
to a designator) to ensure the types are GCC equivalent. If they
are equivalent then it uses gimple assignment and if not then it
copies a structure by field and uses __builtin_strncpy to copy a
string cst into an array. Unions are copied by __builtin_memcpy.
