For C6X, I added a patch to separate out a REG_WORDS_BIG_ENDIAN macro
from WORDS_BIG_ENDIAN. Since the patch was originally for 4.5, it missed
a few new instances in IRA where we need to change which macro we use.
The following patch makes big-endian kernels boot.

Bootstrapped and regression tested on i686-linux; can't affect any
target other than C6X. Normally I'd check it in as obvious, but given
that we're in stage4 I'll ask for an OK.


Bernd
* ira.c (check_allocation): Use REG_WORDS_BIG_ENDIAN, not
	WORDS_BIG_ENDIAN.
	* ira-color.c (setup_profitable_hard_regs, check_hard_reg_p,
	assign_hard_reg): Likewise.

Ok, Bernd.  Thanks.
