[ARM] Enable arm_legitimize_address for Thumb-2
Currently arm_legitimize_address doesn't handle Thumb-2 at all, resulting in
inefficient code. Since Thumb-2 supports similar address offsets use the Arm
legitimization code for Thumb-2 to get significant codesize and performance
gains. SPECINT2006 shows 0.4% gain on Cortex-A57, while SPECFP improves 0.2%.
gcc/
* config/arm/arm.c (arm_legitimize_address): Remove Thumb-2 bailout.
From-SVN: r276961
