[CIL users] Patch to help more precise #line information

[Piramanayagam A. N. <ar...@cs...>]

For a down-stream analysis that reads CIL instrumented files, I need 
#line pragmas for local variables.  I can do that by redefining 'pVDecl' 
in my CIL printer.

But, when printing a function definition, defaultCilPrinterClass doesn't 
add a new line after the opening curly brace.  So, it prints

> foo()
> { int cil_tmp;

This causes a pre-processor error if I print the #line before the 
variable declaration.

> foo()
> { #  12 bar.c
>   int cil_tmp;


This patch adds a new line after the curly brace.  Since pFunDecl is 
private, I cannot solve it by redefining pFunDecl in a subclass of 
defaultCilPrinterClass.

I'm submitting this patch so it can make it in the new release.  Having 
local changes to the CIL tree (albeit 1 line) is still a headache :)
