Add support for SmartMIPS ASE.
gcc/
* optabs.c (expand_binop_directly): New, broken out from...
(expand_binop): Here. Make it try rotating in the other
direction even when the second operand isn't constant.
* config/mips/mips.md (*lwxs): New.
* config/mips/mips.opt (msmartmips): New.
* config/mips/mips.c (mips_lwxs_address_p): New.
(mips_rtx_costs): Make it recognize scaled indexed addressing.
* config/mips/mips.h (TARGET_CPU_CPP_BUILTINS): Define
__mips_smartmips when compiling for TARGET_SMARTMIPS.
(ISA_HAS_ROR): Define for TARGET_SMARTMIPS.
(ISA_HAS_LWXS): New.
(ASM_SPEC): Add -msmartmips/-mno-smartmips.
* doc/invoke.texi (MIPS Options): Document -msmartmips/-mno-smartmips.
* testsuite/gcc.target/mips/smartmips-lwxs.c: New test case.
* testsuite/gcc.target/mips/smartmips-ror-1.c: New test case.
* testsuite/gcc.target/mips/smartmips-ror-2.c: New test case.
* testsuite/gcc.target/mips/smartmips-ror-3.c: New test case.
* testsuite/gcc.target/mips/smartmips-ror-4.c: New test case.
