      - Fix codegen for pc relative constant (e.g. JT) in thumb mode: · 83f35170
      Evan Cheng authored
              .set PCRELV0, (LJTI1_0_0-(LPCRELL0+4))
      LPCRELL0:
              add r1, pc, #PCRELV0
      This is not legal since add r1, pc, #c requires the constant be a multiple of 4.
      Do the following instead:
              .set PCRELV0, (LJTI1_0_0-(LPCRELL0+4))
      LPCRELL0:
              mov r1, #PCRELV0
              add r1, pc
      
      - In thumb mode, it's not possible to use .set generate a pc relative stub
        address. The stub is ARM code which is in a different section from the thumb
        code. Load the value from a constpool instead.
      - Some asm printing clean up.
