b43216ee4a - Off by one bugs in maximum displacement calculation / testing.
- In thumb mode, a new constpool island BB size should be 4 + 2 to
  compensate for the potential padding due to alignment requirement.

b25fe82671 Fixed uninitialized stuff inside LegalizeDAG. Fortunately, the only

e0c2b6b9a8 .set pc relative displacement bug: label should be moved down one instruction
to just before the add r1, pc:

Before:
        .set PCRELV0, (LJTI1_0_0-(LPCRELL0+4))
LPCRELL0:
        mov r1, #PCRELV0
        add r1, pc

Now:
        .set PCRELV0, (LJTI1_0_0-(LPCRELL0+4))
        mov r1, #PCRELV0
LPCRELL0:
        add r1, pc

9d945f78e5 Special epilogue for vararg functions. We cannot do a pop to pc because
there follows a sp increment for the va register save region. Instead issue
a separate pop to another register, increment sp, and then return:
        pop {r4, r5, r6, r7}
        pop {r3}
        add sp, #3 * 4
        bx r3
