tcg-arm: Use R12 for the tcg temporary

R12 is call clobbered, while R8 is call saved. This change
gives tcg one more call saved register for real data.

tcg-arm: Cleanup multiply subroutines

Make the code more readable by only having one copy of the magic
numbers, swapping registers as needed prior to that. Speed the
compiler by not applying the rd == rn avoidance for v6 or later.

tcg-arm: Handle constant arguments to add2/sub2

We get to re-use the _rIN and _rIK subroutines to handle the various
combinations of add vs sub. Fold the << 21 into the opcode enum values
so that we can explicitly add TO_CPSR as desired.

tcg-arm: Improve constant generation

Try fully rotated arguments to mov and mvn before trying movt
or full decomposition. Begin decomposition with mvn when it
looks like it'll help. Examples include

: mov r9, #0x00000fa0
: orr r9, r9, #0x000ee000...
