Alexey Bataev cbecfdfefe [OpenMP] Fix trailing space when printing pragmas, by Joel. E. Denny
Summary:
-ast-print prints omp pragmas with a trailing space.  While this
behavior is likely of little concern to most users, surely it's
unintentional, and it's annoying for some source-level work I'm
pursuing.  This patch focuses on omp pragmas, but it also fixes
init_seg and loop hint pragmas because they share implementation.

The testing strategy here is to add usually just one '{{$}}' per
relevant -ast-print test file.  This seems to achieve good code
coverage.  However, this strategy is probably easy to forget as the
tests evolve.  That's probably fine as this fix is far from critical.
The main goal of the testing is to aid the initial review.

This patch also adds a fixme for "#pragma unroll", which prints as
"#pragma unroll (enable)", which is invalid syntax.

Alexey Bataev a8a9153a37 [OPENMP] Support for -fopenmp-simd option with compilation of simd loops
only.

Added support for -fopenmp-simd option that allows compilation of
simd-based constructs without emission of OpenMP runtime calls.

Serge Pavlov a67a4d2f3c Make output of -ast-print a valid C++ code.
Output generated by option -ast-print looks like C/C++ code, and it
really is for plain C. For C++ the produced output was not valid C++
code, but the differences were small. With this change the output
is fixed and can be compiled. Tests are changed so that output produced
by -ast-print is compiled again with the same flags and both outputs are
compared.

Option -ast-print is extensively used in clang tests but it itself
was tested poorly, existing tests only checked that compiler did not
crash. There are unit tests in file DeclPrinterTest.cpp, but they test
only terse output mode.

Serge Pavlov 7dcc97e7ac Warn if function or variable cannot be implicitly instantiated
With this patch compiler emits warning if it tries to make implicit instantiation
of a template but cannot find the template definition. The warning can be suppressed
by explicit instantiation declaration or by command line options
-Wundefined-var-template and -Wundefined-func-template. The implementation follows
the discussion of http://reviews.llvm.org/D12326.

Alexey Bataev db39021cee [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).

  Assertion failed: (Access != AS_none && "Access specifier is AS_none inside a record decl"), function CheckAccessDeclContext, file clang/lib/AST/DeclBase.cpp, line 690.
