Found by coverity. This is an artifact left over from the original
decaf import which generated the source code for different curves. For
curve 448 this is dead.

Some platforms, cough-DJGPP, fail to compile claiming that requested
alignment is greater than maximum possible. Supposedly original

Debugging asserts had implicit casts that triggered the warnings.
However, instead of making the casts explicit it's more appropriate
to perform checks that ensure that implicit casts were safe.

SPARC condition in __SIZEOF_INT128__==16 is rather performance thing
than portability. Even though compiler advertises int128 capability,
corresponding operations are inefficient, because they are not
directly backed by instruction set.

The original curve448 code was templated to allow for a 25519
implementation. We've just imported the 448 stuff - but a remnant of
the original templated approach remained. This just simplifies that.

We removed various platform specific optimisation files in an earlier
commit. The vector code was related to that and therefore is no longer
required. It may be resurrected at a later point if we reintroduce the
opimtisations.

We already have a constant_time_select() function so, to avoid
confusion/clashing we shouldn't have a second one.

Remove all architecture specific files except for the reference arch_32
version. These files provide archicture specific performance optimisation.
However they have not been integrated yet. In order to avoid review issues
they are removed for now. They may be reintroduced at a later time.
