rev 8713 : SIMD: CMoveVD - .ad is "almost" good. need to make CC in codegen taken rightly from IdealGraph.
Also added (Windows only) an option to stop in debugger after compiled file has been printed.
See compile.cpp: WINDOWS_ONLY(if(method()->has_option("BreakAfterCompilation")) DebugBreak();)
rev 8715 : Making breakpoint after compilation system independent.
rev 8877 : tests from repo commit
rev 8930 : SIMD: cleanup - trailing spaces, tabs
rev 9042 : SIMD: added global flag UseCMov (false).
rev 9043 : SIMD: UseCMov is a must and not set alone in do_vector_loop()
rev 9045 : SIMD: fixed if (!def->is_Bool() || def->in(0) != NULL || def->outcnt() != 1) return NULL;,
      Removed if(method()->has_option("BreakAfterCompilation")) os::breakpoint();
