[commit] New test for complex numbers

I finally got around to fixing up this long-ago approved test.  It passes
everywhere I tried it except for GCC 2.95.3 DWARF-2.  If someone stumbles on
another GCC version that can't handle it, let me know, and we'll update the
xfails.

Checked in HEAD only.

	* gdb.base/completion.exp: Tab-complete "complet" instead of
	"compl".
	* gdb.base/complex.exp, gdb.base/complex.c: New files.
