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
-:        orr   r9, r9, #0x0ff00000
-:        orr   r9, r9, #0xf0000000
+:        mvn   r9, #0x0000005f
+:        eor   r9, r9, #0x00011000
