Fixes these warnings:

../../gcc/gcc/../libgcc/libgcov-util.c: In function 'void tag_counters(unsigned int, int)':
../../gcc/gcc/../libgcc/libgcov-util.c:214:59: warning: 'void* calloc(size_t, size_t)' sizes specified with 'sizeof' in the earlier argument and not in the later argument [-Wcalloc-transposed-args]

I think this can be applied as obvious.

Agreed.  Note that patches need a specially formatted ChangeLog as
part of the commit message,
like for example

libgcc/
            * libgcov-util.c (tag_counters): Swap xcalloc arguments.
            (topn_to_memory_representation): Likewise.

with tabs to indent.

Richard.
