Subject: [PATCH] bignum.cc: fix -Werror=strict-overflow issue

Fixes compilation error with GCC 5.x:

c_src/double-conversion/bignum.cc:102:6: error: assuming signed overflow does not occur when assuming that (X + c) < X is always false [-Werror=strict-overflow]
 void Bignum::AssignDecimalString(Vector<const char> value) {
      ^
