ARM: further improve deprecated diagnosis (LDM)
The ARM ARM states:
LDM/LDMIA/LDMFD:
The SP can be in the list. However, ARM deprecates using these instructions
with SP in the list.
ARM deprecates using these instructions with both the LR and the PC in the
list.
LDMDA/LDMFA/LDMDB/LDMEA/LDMIB/LDMED:
The SP can be in the list. However, instructions that include the SP in the
list are deprecated.
Instructions that include both the LR and the PC in the list are deprecated.
POP:
The SP can only be in the list before ARMv7. ARM deprecates any use of ARM
instructions that include the SP, and the value of the SP after such an
instruction is UNKNOWN.
ARM deprecates the use of this instruction with both the LR and the PC in
the list.
Attempt to diagnose use of deprecated forms of these instructions. This mirrors
the previous changes to diagnose use of the deprecated forms of STM in ARM mode.
