  [ARM] Add some VCMP folding and canonicalisation

The VCMP instructions in MVE can accept a register or ZR, but only as
the right hand operator. Most of the time this will already be correct
because the icmp will have been canonicalised that way already. There
are some cases in the lowering of float conditions that this will not
apply to though. This code should fix up those cases.

  [ARM] Add ARMCC constants to tablegen. NFC

I got tired of looking at magic constants in tablegen files. This adds
condition codes like ARMCCeq and makes use of them.

I also removed the extra patterns for reverse condition codes from
D70296, they should now be covered by the parent commit.

  [ARM] Add ARMVCCThen to tablegen and make use of it. NFC

Similar to the parent, this adds some constants to tablegen to replace
the existing magic values.
