Fix strtod.cc undefined constants (#123)
When DOUBLE_CONVERSION_CORRECT_DOUBLE_OPERATIONS is not defined
there is a build error when -Wall -Werror enabled because
kMaxExactDoubleIntegerDecimalDigits, exact_powers_of_ten and
kExactPowersOfTenSize are used only in else branch of this define
(when it's defined).
