mips.h (MASK_FIX_SB1): Bump.
* config/mips/mips.h (MASK_FIX_SB1): Bump.
(MASK_FIX_R4400, TARGET_FIX_R4400): New macros.
(TARGET_SWITCHES): Add -mfix-r4400 and -mno-fix-r4400.
* config/mips/mips.c (mips_output_division): Fill the branch delay
slot with a nop if TARGET_FIX_R4000. Extend R4000 workarounds to
TARGET_FIX_R4400.
(mips_output_division): Adjust accordingly.
(override_options): Make -march=r4400 imply -mfix-r4400 by default.
* doc/invoke.texi: Document -mfix-r4400 and new errata workarounds.
