tcg/arm: improve constant loading
Improve constant loading in two ways: - On all ARM versions, it's possible to load 0xffffff00 = -0x100 using the mvn rd, #0. Fix the conditions. - On <= ARMv6 versions, where movw and movt are not available, load the constants using mov and orr with rotations depending on the constant to load. This is very useful for example to load constants where the low byte is 0. This reduce the generated code size by about 7%. Also fix the coding style at the same time.
