do not spill dead phis
...
Regalloc will be able to handle these spurious phis,
however, some other spurious dead instructions can be
emitted. It would be better to get rid of them upfront;
maybe by modifying isel, or by inserting a proper dce
pass. An example of that undesirable behavior is
exposed below.
@l1
%foo =w ...
@l2
%dead =w phi @l1 %foo, ...

complete fp support for small structs
...
There is an oddity/bug though, we use OStorel to store possibly
fp registers. Gas does not complain, but this is wrong. The
fix is probably to have a simple OStore, like in the OLoad case.

patch minic for new comparisons

This solved one pending bug: comparisons of long
variables are now compiled properly. A bug for
comparisons < and <= of pointers remain, it is
related to signedness, not width. This can be
easily fixed by the reader!
