Chih-Hung Hsieh 765c1ea6d7 Use newest clang static analyzers.

* When WITH_STATIC_ANALYZER is set and non-zero, and clang compiler is used,
  call new clang ccc-analyzer or c++-analyzer.
* Otherwise, if WITH_SYNTAX_CHECK is set and non-zero,
  call compiler with -fsyntax-only.
* Replace "--sysroot=path" with "--sysroot path", to work with ccc-analyzer.
* ccc-analyzer executes the original compilation command to generate
  object files before calling clang with --analyze to do static analysis.
* When clang is called with --analyze, macro __clang_analyzer__ is defined.
