re PR target/46881 (arm_preferred_rename_class uses keyword class as parameter name) 

PR target/46881
	* doc/tm.texi: Regenerate.
	* target.def: Fix "preferred" spelling.  Refer to rclass by its
	exact name.
	* config/arm/arm.c (arm_preferred_rename_class): Rename parameter class
	to rclass.

@deftypefn {Target Hook} reg_class_t TARGET_PREFERRED_RENAME_CLASS (reg_class_t @var{rclass})
A target hook that places additional preference on the register class to use when it is necessary to rename a register in class @var{class} to another class, or perhaps @var{NO_REGS}, if no prefered register class is found or hook @code{preferred_rename_class} is not implemented. Sometimes returning a more restrictive class makes better code. For example, on ARM, thumb-2 instructions using @code{LO_REGS} may be smaller than instructions using @code{GENERIC_REGS}. By returning @code{LO_REGS} from @code{preferred_rename_class}, code size can be reduced.
