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
