fix the "pasting formed 'a]', an invalid preprocessing token"

diagnostic to include the full instantiation location for the
invalid paste.  For:

#define foo(a, b)  a ## b
#define bar(x) foo(x, ])
bar(a)
bar(zdy)

Instead of:

t.c:3:22: error: pasting formed 'a]', an invalid preprocessing token
#define foo(a, b)  a ## b
                     ^
t.c:3:22: error: pasting formed 'zdy]', an invalid preprocessing token

we now produce:

t.c:7:1: error: pasting formed 'a]', an invalid preprocessing token
bar(a)
^
t.c:4:16: note: instantiated from:
#define bar(x) foo(x, ])
               ^
t.c:3:22: note: instantiated from:
#define foo(a, b)  a ## b
                     ^
t.c:8:1: error: pasting formed 'zdy]', an invalid preprocessing token
bar(zdy)
^
t.c:4:16: note: instantiated from:
#define bar(x) foo(x, ])
               ^
t.c:3:22: note: instantiated from:
#define foo(a, b)  a ## b
                     ^
