Subject: [PATCH 1/2] [flang][OpenMP] General utility to get directive id from
AST node
Fortran::parser::omp::GetOmpDirectiveName(t) will get the OmpDirectiveName
object that corresponds to construct t. That object (an AST node) contains
the enum id and the source information of the directive.
Replace uses of extractOmpDirective and getOpenMPDirectiveEnum with the
new function.
