[svn r98] Added support for std.c.stdlib.alloca via pragma(LLVM_internal, "alloca"). Added support for array .sort and .reverse properties. Fixed some bugs with pointer arithmetic. Disabled some DMD AST optimizations that was messing things up, destroying valuable information. Added a KDevelop project file, this is what I use for coding LLVMDC now :) Other minor stuff.
