Thats an interesting idea. That would allow us to swap in a direct call 
to the debug allocation routines, too.

However, one thing I worry about with using indirect dispatch for 
everything, though, is that it makes the compiler's asm output a whole 
lot less readable. A solution for that might be to allow the name of the 
target decl of the call to persist through gimplification somehow, so 
that -fdebug-asm can print the name of the function it thinks its 
calling alongside the call instruction.
