And so I did.  Attached is an updated patch that adds the address space
parameter to the address_cost function.  I hope that this change does
not reset the ACKs so far:

[x] target-independent bits
[ ] alpha     [ ] arm       [ ] avr         [ ] bfin
[ ] cr16      [ ] cris      [ ] epiphany    [ ] i386
[ ] ia64      [ ] iq2000    [ ] lm32        [ ] m32c
[ ] m32r      [ ] mcore     [ ] mep         [x] microblaze
[x] mips      [ ] mmix      [x] mn10300     [ ] pa
[ ] rs6000    [ ] rx        [ ] s390        [ ] score
[x] sh        [ ] sparc     [ ] spu         [ ] stormy16
[ ] v850      [ ] vax       [ ] xtensa

Tested with 'make all-gcc' on SH xgcc and i386 native build.
No functional changes, except on MIPS, as requested by Richard
Sandiford.

Cheers,
Oleg
