[svn r233] Added: -oq command line option for writing fully qualified object names. Added: started support for x86 80bit floating point. Changed: aggregates passed by value now use the llvm 'byval' parameter attribute, also lays ground work for using other attributes. Changed: eliminated a lot more std::vectorS, these showed up pretty much at the top when profiling! Changed: performed other misc. cleanups. Changed: halt expression now call the new llvm trap intrinsic instead of an assert(0). Changed: dstress suite now passes -O0 by default, this only eliminates unreferenced globals, which speeds up linking quite a bit.
