[lto] c-common.c: Remove an unused variable.

[Kazu Hirata]

Hi,

Attached is a patch to remove an unused variable.

While this patch seems irrelevant to the LTO branch at first glance,
it is actually relevant.  After I convert TYPE_ARG_TYPES to a
TREE_VEC, I am planning to walk a TREE_VEC like so:

  for (i = 0; i < TREE_VEC_LENGTH (arg_types); i++)

It would be confusing to have an extra iterator, namely "number", in
addition to "i".

Tested on x86_64-pc-linux-gnu.  Committed to the LTO branch as
obvious.

	write-only variable.
