This causes the following on hppa*-*-* (32-bit):
../../gcc/gcc/reload1.c: In function 'rtx_def* gen_reload(rtx, rtx, int, reload_
type)':

There are a number of problems in the interaction between secondary
memory and subregs. If we reload the inner of a subreg, we forget about
this when deciding whether to use secondary memory, and just use
REGNO_REG_CLASS on the (now reloaded) inner.
Also, we don't really know what to do if we get
