[PATCH v3] Fix gdb crash when trying to print the address of a synthetic C++ reference

[Martin Galvan]

Sorry, I didn't notice there was a separate ChangeLog for the testsuite.
This should be:

2016-04-04  Martin Galvan  <martin.galvan@tallertechnologies.com>

	* valops.c (value_addr): For C++ references, set the copied value's
	enclosing_type as well.

	testsuite/
	* gdb.dwarf2/implref.exp: New file.
