Why do we ever perform explicit make_decl_rtl calls when
DECL_RTL will do that when necessary?
I noticed this over the last few days while trying to discover what
causes GC fragmentation and large amounts of dead RTL. Just think of
all the DECL_RTL generated from the system header files while
compiling C, most of which will be never accessed again during the
compilation as far as I can tell.
