Tomas Lindquist Olsen 3b4c818082 [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.
