2d85458c52 Fix Transforms/InstCombine/2007-02-01-LoadSinkAlloca.ll, a serious code 
pessimization where instcombine can sink a load (good for code size) that
prevents an alloca from being promoted by mem2reg (bad for everything).

618f24b0ed Fix bugs in the inliner having to do with single-entry phi nodes and valuemap 
updating.  These were exposed by Devang's recent passmgr changes (with
non-default passorderings) because now the inliner can be interleved with
the LCSSA pass.

88b703eec4 - 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.

d3dc2eefc2 .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

439dcbedba 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
