[PATCH 01/14] C++: preserve locations within build_address

[David Malcolm]

This is needed for the locations of string literals to be usable,
otherwise the ADDR_EXPR has UNKNOWN_LOCATION, despite wrapping
a node with a correct location_t.

gcc/cp/ChangeLog:
        * typeck.c (build_address): Use location of operand when building
        address expression.
