(lp#520366) + * optimization: the compiler is now more aware of the type of the underlying + storage vector for multidimensional simple arrays resulting in better code + for accessing such arrays. + * optimization: passing NIL as the environment argument to TYPEP no longer + inhibits optimizing it. (lp#309788) + * optimization: more efficient register usage when handling single-float + arguments on x86-64.
