[PATCH] [OPENMP] Codegen for 'num_threads' clause in 'parallel' directive

[Alexey Bataev]

Hi doug.gregor, hfinkel, rjmccall, rsmith, fraggamuffin, ejstotzer,

This patch generates call to "__kmpc_push_num_threads(ident_t *loc, kmp_int32 global_tid, kmp_int32 num_threads);" library function before calling "__kmpc_fork_call" each time there is an associated "num_threads" clause in the "omp parallel" directive.
