  Log Message:
  [flang][OpenMP] Add some semantic checks for threadprivate and declare target directives

This supports the following checks for THREADPRIVATE Directive:
[5.1] 2.21.2 THREADPRIVATE Directive
A threadprivate variable must not appear in any clause except the
copyin, copyprivate, schedule, num_threads, thread_limit, and if clauses.

This supports the following checks for DECLARE TARGET Directive:
[5.1] 2.14.7 Declare Target Directive
A threadprivate variable cannot appear in the directive.

Besides, procedure name and the entity with PARAMETER attribute cannot
be in the threadprivate directive. The main program name and module name
cannot be in the threadprivate directive and declare target directive.
There is no clear description or restriction about the entity with
PARAMETER attribute in OpenMP 5.1 Specification, and a warning is given.
