invoke.texi: Document new MIPS -mllsc and -mno-llsc options.
* doc/invoke.texi: Document new MIPS -mllsc and -mno-llsc options.
* doc/install.texi: Document new --with-llsc and --without-llsc
options.
* config.gcc: Handle --with-llsc and --without-llsc configure options.
* config/mips/mips.md (sync, memory_barrier): Wrap sync instrunction
in %| and %- operand codes. Depend on GENERATE_SYNC instead of
ISA_HAS_SYNC.

* config/mips/mips.opt (mllsc): New option.
* config/mips/mips.c (mips_llsc): Define variable.
(mips_handle_option): Handle mllsc option.
(override_options): Set mips_print_operand_punct for '|' and '-'.
(print_operand): Add new %| and %- operand codes.
* config/mips/mips.h (mips_llsc_setting): New enum type.
(mips_llsc): Declare.
(OPTION_DEFAULT_SPECS): Add llsc handling.
(GENERATE_SYNC): New macro.
(GENERATE_LL_SC): New macro.
(MIPS_COMPARE_AND_SWAP, MIPS_SYNC_OP, MIPS_SYNC_OLD_OP,
MIPS_SYNC_NEW_OP, MIPS_SYNC_NAND, MIPS_SYNC_OLD_NAND,
MIPS_SYNC_NEW_NAND, MIPS_SYNC_EXCHANGE): Wrap instructions
in %| and %- operand codes.
