9c7bfc232e Forgot to commit this earlier. Its part of the simplify-libcalls 
enhancement for ffs, ffsl, and ffsll optimizations. We can't do the opt
unless we also have the at least ffsll function. Notably SVR4 doesn't.

9cd1000c52 Changes for ffs lib call simplification: 
* Check for availability of ffsll call in configure script
* Support ffs, ffsl, and ffsll conversion to constant value if the argument
  is constant.

214f1a8cf9 Make sure to preserve the calling convention when changing an invoke into 
a call.  This fixes Prolangs-C++/deriv2, kimwitu++, and Misc-C++/bigfib
on X86 with -enable-x86-fastcc.

adde8b1a71 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.

c0c6680744 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.
