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.

The predicate IsHostAssocited() was implemented in a way that would
return true only for cases of host association into a module or inner
subprogram. Technically, the use of a name in a BLOCK construct
that is not declared therein is considered in the Fortran standard
to also be a form of host association, and this matters when doing
error checking on DATA statements.

This patch improves semantic checks for hint clause.
It checks "hint-expression is a constant expression
that evaluates to a scalar value with kind
`omp_sync_hint_kind` and a value that is a valid
synchronization hint."

As OpenMP 5.0, for firstprivate, lastprivate, copyin, and copyprivate
clauses, if the list item is a polymorphic variable with the allocatable
attribute, the behavior is unspecified.
