Subject: patch to fix a typo in ira.c

Xingxing Pan found a typo in IRA code.  Here is the patch to fix it.

The patch was bootstrapped on x86/x86-64.  I did not find code 
generation difference on x86/x86-64, s390, ppc, and arm on variety 
tests.   The code might make some small difference on other targets though.

	* ira.c (setup_class_translate_array): Use aclass instead of cl
	for classes not fully covered by allocno classes.
