920c0aa9c2 Pass i64 values correctly split in reg/mem to fastcc calls.
This fixes fourinarow with -enable-x86-fastcc.

239738a162 Use target-specific nodes for calls. This allows the fastcc code to not have
to do ugly hackery to avoid emitting code like this:

   call foo
   mov vreg, EAX
   adjcallstackup ...

If foo is a fastcc call and if vreg gets spilled, we might end up with this:

   call foo
   mov [ESP+offset], EAX     ;; Offset doesn't consider the 12!
   sub ESP, 12

Which is bad.  The previous hacky code to deal with this was A) gross B) not
good enough.  In particular, it could miss cases and emit the bad code above.
Now we always emit this:

   call foo
   adjcallstackup ...
   mov vreg, EAX

directly.

This makes fastcc with callees poping the stack work much better.  Next
stop (finally!) really is tail calls.

67649dfc32 use a target-specific node and custom expander to lower long->FP to FILD64m.
This should fix some missing symbols problems on BSD and improve performance
of programs that use that operation.
