IMPALA-3308: Get expr-test passing on PPC64LE

When using gcc 5+ (which introduced a new library ABI that includes new
implementations of std::string) to build Impala, the copy of the class
ExprValue(std::string) would be unsafe as string_val.ptr will not be
updated to point to the relocated string_data.data().

In order to solve this issue, we need to change how we initialize value_
so that it is initialized in-place, rather than created as a temporary
on the stack and then copied.
