Fix var tracking ICE due to reorg.

If during reorg we delete a code label, and as a result we decide to
delete all the code following that label, we hit this condition in
jump.c:delete_related_insns():

  if (was_code_label && prev && BARRIER_P (prev))

which passes and then we proceed to delete insns until we hit a
non-deleted code label.

During this traversal, we can end up deleting a CALL, but in doing so
we will leave the var tracking note for the call arguments around.

Later in dwarf2_var_location() we will ICE, because we can't find the
CALL when we search backwards for it.

The note searching scheme in the fix below is cribbed from code in
try_split() which has to handle a similar problem.

PR preprocessor/7263 - Avoid pedantic warnings on system headers macro tokens

Now that we track token locations accross macro expansions, it would
be cool to be able to fix PR preprocessor/7263 for real.  That is,
consider this example where we have a system header named header.h
like this:

#define _Complex __complex__ #define _Complex_I 1.0iF

and then a normal C file like this:

    #include "header.h"

    static _Complex float c = _Complex_I;

If we compile the file with -pedantic, the usages of _Complex or
_Complex_I should not trigger any warning, even though __complex__ and
the complex literal are extensions to the standard C.

They shouldn't trigger any warning because _Complex and _Complex_I are
defined in a system header (and expanded in normal user code).

To be able to handle this, we must address two separate concerns.

First, warnings about non-standard usage of numerical literals are emitted
directly from within libcpp.  So we must teach libcpp's parser for numerical
literals to use virtual locations, instead of the spelling
location it uses today.  Once we have that, as the diagnostics machinery
already knows how to avoid emitting errors happening on tokens that come from
system headers, we win.

Second, there is the issue of tracking locations for declaration
specifiers, like the "_Complex" in the declaration:

static _Complex float c;

For that, we need to arrange for each possible declaration specifier
to have its own location, because otherwise, we'd warn on e.g, on:

    _Complex float c;

but not on:

    static _Complex float c;

So this patch addresses the two concerns above.  It's actually a
follow-up on an earlier patch[1] I wrote as part of my initial work on
virtual locations.  We then agreed[2] that the second concern was
important to address before the patch could get a chance to go in.
