d: Expand bsr intrinsic as `clz(arg) ^ (argsize - 1)'
As well as removing unnecessary casts, this results in less temporaries
being generated during the initial gimple lowering pass. Otherwise the
code generated is identical to the former intrinsic expansion.
gcc/d/ChangeLog:
* intrinsics.cc (expand_intrinsic_bsf): Fix comment.
(expand_intrinsic_bsr): Use BIT_XOR_EXPR instead of MINUS_EXPR.
