[PATCH 1/5] Allow *_HARD_REG_SET arguments to be const

Patch 4 needs to pass a const HARD_REG_SET to AND/COPY_HARD_REG_SET.
This patch allows that for all intent-in arguments.


gcc/
	* hard-reg-set.h (COPY_HARD_REG_SET, COMPL_HARD_REG_SET)
	(AND_HARD_REG_SET, AND_COMPL_HARD_REG_SET, IOR_HARD_REG_SET)
	(IOR_COMPL_HARD_REG_SET): Allow the "from" set to be constant.
