[patch, testsuite] Change free() decl in g++.dg/tree-ssa/copyprop.C

[Steve Ellcey]

The test g++.dg/tree-ssa/copyprop.C is failing on IA64 HP-UX because the
test includes several headers (map, vector, iostream) and then has
'extern void free (void *);'.  On HP-UX we indirectly include cstdlib
from the other header files so we get a warning message about free()
being  redefined.  Since we are already including header files it seems
like we should include cstdlib to define free() instead of having an
explicit definition of free() in the source file.

Tested on IA64 HP_UX and Linux with no regression.

OK for checkin?

	* g++.dg/tree-ssa/copyprop.C: Use include to define free().
