[Bug gas/709] New: GAS does not give enough warnings about wrong usage of non shortcuttable registers.

[ramana dot radhakrishnan at codito dot com]

Consider the following test case on the ARC . 

                
.extCoreRegister roshortcutextcore, 38, r, can_shortcut
.extCoreRegister rwshortcutextcore, 39, r|w, can_shortcut
.extCoreRegister wshortcutextcore , 40, w, can_shortcut
.extCoreRegister ronoshortcutextcore, 41, r, cannot_shortcut
.extCoreRegister wonoshortcutextcore , 42, w,cannot_shortcut
.extCoreRegister rwnoshortcutextcore , 43, r|w, cannot_shortcut

extCoreTest:
        add r0, roshortcutextcore, r1
        ld rwshortcutextcore, [r2]
        add r0,rwshortcutextcore,r1
        ;;  No warning about shortcutting given.
        ld rwnoshortcutextcore, [r3] 
        add r0, rwnoshortcutextcore,r1 ;; GAS ought to give a warning here.
