[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.

module arrays5;
void main()
{
    auto arr = new float[5];
    {arr[4] = 1f;}
    {assert(arr[0] !<>= 0f);}
    {assert(arr[1] !<>= 0f);}
    {assert(arr[2] !<>= 0f);}
    {assert(arr[3] !<>= 0f);}
    {assert(arr[4] == 1f);}
}
