[PATCH] line numbering

[Nathan Sidwell]

Hi,
this patch changes the interface of init_function_start.
Rather than be given a file and line number tuple, it uses the
DECL_SOURCE_LOCATION of the FUNCTION_DECL it is supplied with.

In the places were it was not immediately obvious that the
previously passed tuple was identical to the DECL's location
I added asserts at those call sites to verify. I found no
failures. (The asserts were a check for my understanding, and
are removed from this patch.)

booted & tested on i686-pc-linux-gnu, ok?
