Add some more MC tests for ARM arithmetic instructions that update or don't
...
update the condition codes. These come from my test generator and are just
the ones that MC currently assembles correctly.

Add support for parsing ARM arithmetic instructions that update or don't update
...
the condition codes. Where the ones that do have an 's' suffix and the ones
that don't don't have the suffix. The trick is if MatchInstructionImpl() fails
we try again after adding a CCOut operand with the correct value and removing
the 's' if present. Four simple test cases added for now, lots more to come.

Rename getAddrModeImm12OpValue to getAddrModeImmOpValue and expand it to work
...
with immediates up to 16-bits in size. The same logic is applied to other LDR
encodings, e.g. VLDR, but which use a different immediate bit width (8-bits in
VLDR's case). Removing the "12" allows it to be more generic.

add simple support for addrmode5 operands, allowing
...
vldr.64 to work. I have no idea if this is fully right, but
it is in the right direction.

most simple arm instructions match correctly now,

it looks like we're not handling [] operands though

fix the asmmatcher generator to handle targets with no RegisterPrefix
...
(like ARM) correctly. With this change, we can now match "bx lr"
because we recognize lr as a register.
