Class-ify lm_info_windows

This patch makes lm_info_windows a "real" class.  It initializes the field
and replaces XCNEW/xfree with new/delete.

gdb/ChangeLog:

	* windows-nat.c (struct lm_info_windows): Initialize field.
	(windows_make_so): Allocate lm_info_windows with new.
	(windows_free_so): Free lm_info_windows with delete.
