re PR c++/90010 (valgrind error with snprintf and -Wall)

PR c++/90010
* gimple-ssa-sprintf.c (target_to_host): Fix handling of targstr
with strlen in between hostsz-3 and hostsz-1 inclusive when no
translation is needed, and when translation is needed, only append
... if the string length is hostsz or more bytes long.  Avoid using
strncpy or strcat.

* gcc.dg/pr90010.c: New test.
