[svn r296] Removed: the 'suite' dir, it never took off! Fixed: foreach statement, key-type checks were buggy. Fixed: setting LLVMDC versions on the command line is now an error. Fixed: array compare runtime had incorrect param attrs on call. Fixed: index expressions on dynamic array slices w/o storage was broken. Fixed: scope classes had incorrect finalization in some cases. Fixed: when outputting !ClassInfoS !OffsetTypeInfoS, static class members were trying to be included, crashing the compiler. Fixed: calling LLVMDC with -inline but not any -O option caused assertion failure. Changed: the runtime now uses a single interface to "get" to !TypeInfoS, part of eliminating duplicate !TypeInfo codegen.
