69520ed67a Fix 2005-05-12-Int64ToFP
The issue is there is no unsigned -> double conversion, only signed.  So I
need to test the sign and do a different thing depending on it.  Ideally
this should be in a different BB, but in the mean time, I use a branch
free method.

57ebf3d6a8 Since everyone else has "fixed" this file, might as well join in the fun.

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.
