tailc, expand: Small incremental tweak to tail call dump [PR119718]

Here is an optional incremental tweak to the previous patch.
Instead of

./xgcc -B ./ -S -O2 -fdump-{tree-tailc,rtl-expand}-details pr119718.c ; grep -B1 '^\(;; \)\?Cannot tail-call:' pr119718.c.*
pr119718.c.222t.tailc-_7 = bar (0);
pr119718.c.222t.tailc:Cannot tail-call: call invocation refers to locals
--
pr119718.c.270r.expand-;; foo (1, 2, 3, 4, 5, 6, 7) [tail call]
pr119718.c.270r.expand:;; Cannot tail-call: callee required more stack slots than the caller

this dumps

./xgcc -B ./ -S -O2 -fdump-{tree-tailc,rtl-expand}-details pr119718.c ; grep '^\(;; \)\?Cannot tail-call:' pr119718.c.*
pr119718.c.222t.tailc:Cannot tail-call: call invocation refers to locals: _7 = bar (0);
pr119718.c.270r.expand:;; Cannot tail-call: callee required more stack slots than the caller: foo (1, 2, 3, 4, 5, 6, 7) [tail call]

	at the end of the ;; Cannot tail-call line rather than on the
