This fixes spurious testsuite FAILs in C++ that occur because we
do not do fancy printing when referece vs. pointer types occur.

Bootstrapped and tested on x86_64-unknown-linux-gnu, applied to the 
branch.

Richard.

	* tree-pretty-print.c (dump_generic_node): Ignore pointer
	vs. reference type when doing fancy MEM_REF dumping.
