Hook up global function and variable handling. We can now compile:

int X, bar(int,int,int);
short Y;

double foo() {
  return bar(X, Y, 3);
}

into:

@X = external global i32                ; <i32*> [#uses=1]
@Y = external global i16                ; <i16*> [#uses=1]

define double @foo() {
entry:
        %tmp = load i32* @X             ; <i32> [#uses=1]
        %tmp1 = load i16* @Y            ; <i16> [#uses=1]
        %promote = sext i16 %tmp1 to i32                ; <i32> [#uses=1]
        %call = tail call i32 @bar( i32 %tmp, i32 %promote, i32 3 )             ; <i32> [#uses=1]
        %conv = sitofp i32 %call to double              ; <double> [#uses=1]
        ret double %conv
}

declare i32 @bar(i32, i32, i32)
