[OPENMP] -fopenmp enables OpenMP support (fix for http://llvm.org/PR23492) -fopenmp turns on OpenMP support and links libiomp5 as OpenMP library. Also there is -fopenmp={libiomp5|libgomp} option that allows to override effect of -fopenmp and link libgomp library (if -fopenmp=libgomp is specified).

[OPENMP 4.1] Parsing/sema analysis for extended format of 'if' clause. OpenMP 4.1 added special 'directive-name-modifier' to the 'if' clause. Format of 'if' clause is as follows: ``` if([ directive-name-modifier :] scalar-logical-expression) ``` The restriction rules are also changed. 1. If any 'if' clause on the directive includes a 'directive-name-modifier' then all 'if' clauses on the directive must include a 'directive-name-modifier'. 2. At most one 'if' clause without a 'directive-name-modifier' can appear on the directive. 3. At most one 'if' clause with some particular 'directive-name-modifier' can appear on the directive. 'directive-name-modifier' is important for combined directives and allows to separate conditions in 'if' clause for simple sub-directives in combined directive. This 'directive-name-modifier' identifies the sub-directive to which this 'if' clause must be applied. llvm-svn: 246747
