Hi!
On some targets implicit_built_in_decls[BUILT_IN_SNPRINTF] is NULL,
but as we want only the return type of the snprintf function
and fold_builtin_snprintf in that case is only used when
__builtin_* variant is used explicitly, using built_in_decls
is better and avoids the ICE.
Bootstrapped/regtested on x86_64-linux and i686-linux, tested
on the testcase with cross to cris-elf, committed to trunk
as obvious.

* builtins.c (fold_builtin_snprintf): Convert to type of
built_in_decls[BUILT_IN_SNPRINTF] retval instead of
implicit_built_in_decls[BUILT_IN_SNPRINTF] retval.
