805543068e ARMLoadStoreOptimizer invalidates register liveness. 
This pass tries to update kill flags, but there are still many bugs.
Passes after the load/store optimizer don't need accurate liveness, so
don't even try.

e279f5953e ARM has a peephole optimization which looks for a def / use pair. The def 
produces a 32-bit immediate which is consumed by the use. It tries to 
fold the immediate by breaking it into two parts and fold them into the
immmediate fields of two uses. e.g
       movw    r2, #40885
       movt    r3, #46540
       add     r0, r0, r3
=>
       add.w   r0, r0, #3019898880
       add.w   r0, r0, #30146560
;
However, this transformation is incorrect if the user produces a flag. e.g.
       movw    r2, #40885
       movt    r3, #46540
       adds    r0, r0, r3
=>
       add.w   r0, r0, #3019898880
       adds.w  r0, r0, #30146560
Note the adds.w may not set the carry flag even if the original sequence
would.

aaa1e2f820 Require a base pointer for stack realignment when SP may vary dynamically. 
ARMBaseRegisterInfo::canRealignStack was checking for variable-sized objects
but not for stack adjustments around calls.  Use hasReservedCallFrame() to
check for both.  The hasBasePointer function was already correctly checking
both conditions, so the effect of this was that a base pointer would be used
without checking whether the base pointer register could be reserved. I don't
have a small testcase for this.

5aeff3171c Check if we can handle the arguments of a call (and therefore the call) in 
fast-isel before emitting code. If the program bails after code was emitted,
then it could lead to the stack being adjusted more than once (two
CALLSEQ_BEGINs emitted) but being adjuste back only once after the call. This
leads to general badness and gnashing of teeth.

be7cf2b377 ARM ldm/stm register lists can be out of order.

numerical order, not the order they're in the list, but it's legal. vldm/vstm
