64c88d741e bugfix: When the source register of CALL_NOLINK was LR, the following code was emitted: 
mov lr, pc
    bx lr
So, the function was not called.

fa775d09c6 Special LDR instructions to load from non-pc-relative constantpools. These are 
rematerializable. Only used for constant generation for now.

b38cba928e ARM callseq_end should have a input flag operand so it would be scheduled right after the call.

c60e76d139 - Fix codegen for pc relative constant (e.g. JT) in thumb mode: 
.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.
