This patch adds lowering support for default clause. 1. During symbol resolution in semantics, should the enclosing context have a default data sharing clause defined and a `parser::Name` is not attached to an explicit data sharing clause, the `semantics::Symbol::Flag::OmpPrivate` flag (in case of default(private)) and `semantics::Symbol::Flag::OmpFirstprivate` flag (in case of default(firstprivate)) is added to the symbol. 2. During lowering, all symbols having either `semantics::Symbol::Flag::OmpPrivate` or `semantics::Symbol::Flag::OmpFirstprivate` flag are collected and privatised appropriately.
