[OPENMP] Codegen for 'omp critical' directive.
This patch adds codegen for constructs:
#pragma omp critical [name]
<body>
It generates global variable ".gomp_critical_user_[name].var" of type int32[8]. Then it generates library call "kmpc_critical(loc, gtid, .gomp_critical_user_[name].var)", code for <body> statement and final call "kmpc_end_critical(loc, gtid, .gomp_critical_user_[name].var)".
