Add an interface to the go Linemap class to allow clients to ask for the
line number for a Location (for debugging dumps), so as to move some
gcc-specific location code into the back end.

* go-linemap.cc (Gcc_linemap::location_line): New method.

Change the compiler to use the new routines. Drop the separation of
small and large values when sending on a channel. Allocate the select
struct on the stack. Remove the old C implementation of channels. Adjust
the garbage collector for the new data structure.
Bring in part of the tracing code, enough for the channel code to call.
Bump the permitted number of allocations in one of the tests in
context_test.go. The difference is that now receiving from a channel
allocates a sudog, which the C code used to simply put on the
stack. This will be somewhat better when we port proc.go.

Turned out that there where a few () around macro args uses missing.
One real problem with it was detected with the int-in-bool-context in
the definition of DBX_REGISTER_NUMBER. But while being at it I've
also tried to fix other places where brackets might be missing.

Many POSIX systems have the bad habit of not restarting interrupted
syscalls. On these systems it's up to the user to check for an error
with errno == EINTR and restart manually. This patch does this for
libgfortran, so that GFortran users don't have to do it.
