[PATCH] Fix "psb CSYNC" and "bti C".

[apinski@marvell.com]

From: Andrew Pinski <apinski@marvell.com>

psb CYSNC was not finding that CSYNC was a correct spelling.
The problem was upper case version was being put in the
wrong hashtable.  This fixes the problem by using the
correct hashtable.
Also adds testcases for the upper case versions.

OK?  Tested for aarch64-linux-gnu with no test failures.

Thanks,
Andrew Pinski


        * config/tc-aarch64.c (md_begin): Use correct
        hash table for uppercase version of hint.
        * testsuite/gas/aarch64/system-2.s: Extend psb case to uppercase.
        * testsuite/gas/aarch64/system-2.d: Update.
