8ae4f062e4 ARM: peephole optimization to remove cmp instruction 
This patch will optimize the following cases:
  sub r1, r3 | sub r1, imm
  cmp r3, r1 or cmp r1, r3 | cmp r1, imm
  bge L1

TO
  subs r1, r3
  bge  L1 or ble L1

If the branch instruction can use flag from "sub", then we can replace
"sub" with "subs" and eliminate the "cmp" instruction.

5fc2187a02 Generate AVX/AVX2 shuffles even when there is a memory op somewhere else in the program. 
Starting r155461 we are able to select patterns for vbroadcast even when the load op is used by other users.

397fc4874e Add an MF argument to TRI::getPointerRegClass() and TII::getRegClass(). 
The getPointerRegClass() hook can return register classes that depend on
the calling convention of the current function (ptr_rc_tailcall).

So far, we have been able to infer the calling convention from the
subtarget alone, but as we add support for multiple calling conventions
per target, that no longer works.

fd87839a48 Add TRI::getCommonSuperRegClass(). 
This function is a generalization of getMatchingSuperRegClass() to the
symmetric case where both sides are using a sub-register index. It will
find a super-register class and sub-register indexes that make this
diagram commute:

                                   PreA
                       SuperRC  ---------->  RCA

                          |                   |
                          |                   |
                     PreB |                   | SubA
                          |                   |
                          |                   |
                          V                   V

                         RCB    ----------> SubRC
                                   SubB

This can be used to coalesce copies like:

  %vreg1:sub16 = COPY %vreg2:sub16; GR64:%vreg1, GR32: %vreg2
