* Makefile.in (GTFILES): Add $(srcdir)/reload.h.
	* gengtype.c (open_base_files): Include reload.h in ifiles.
	* reload.h (reg_equiv_memory_loc_varray): Declare.
	* reload1.c (reg_equiv_memory_loc_varray): New variable.
	(init_reload): Initialize it.
	(reload): Instead of freeing reg_equiv_memory_loc, 'grow'
	reg_equiv_memory_loc_varray to size 0.
	* ra.c (reg_alloc): Allocate reg_equiv_memory_loc by
	growing reg_equiv_memory_loc_varray to the desired size.

ought to be used instead.
Before processing the first insn of the function, call `init_reload'.
init_reload actually has to be called earlier anyway.
To scan an insn, call `find_reloads'. This does two things:
1. sets up tables describing which values must be reloaded
