[llvm-commits] Fix K&R prototype handling

This patch causes us to compile functions like:

p1 (f2, l)
float f2; short l;  {
   printf("%d\n", l);


define i32 %p1(double %f2, i32 %l) {

instead of:

define i32 %p1(float %f2, i16 %l) {

due to K&R promotion rules.  This fixes a miscompilation of  
SingleSource/UnitTests/2007-01-04-KNR-Args.c on PowerPC at -O0.
