Fix integer-overflow problem in intarray's g_int_decompress().
An array element equal to INT_MAX gave this code indigestion,
causing an infinite loop that surely ended in SIGSEGV. We fixed
some nearby problems awhile ago (cf 757c5182f) but missed this.
Report and diagnosis by Alexander Lakhin (bug #18273); patch by me
