Anonymous string is one exception that the back end does
need to generate storage on (read only) data section.
Currently in order to determine a symbol is anonymous string,
we can test:
symbol is array
and symbol has no ident.
and symbol base type is char.
and symbol initializer is a string expression.
This patch add a bitfield to easier identify an anonymous string.
