Changed the handling of variadic intrinsics a bit. Removed the -fp80 option and made real be 80bit floats on X86, this is what the D spec really says it should be and fixes a bunch of issues. Changed the handling of parameter attributes to a bit more generalized approach. Added sext/zext attributes for byte/short/ubyte/ushort parameters, fixes #60 . Parameter attribs now properly set for intrinsic calls if necessary. Made the tango.math.Math patch less intrusive. Fixed/added some mini tests.

module tangotests.marray2;

void main()
{
    int[][] ma = new int[][](2,4);
    assert(ma.length == 2);
    assert(ma[0].length == 4);
    assert(ma[1].length == 4);
    ma[0][3] = 32;
    ma[1][2] = 123;
    ma[0][0] = 55;
    assert(ma[0][3] == 32);
    assert(ma[1][2] == 123);
    assert(ma[0][0] == 55);
}
