085ea1b633 Fixed an ARM disassembler bug where it does not handle STRi12 correctly because an extra
register operand was erroneously added.  Remove an incorrect assert which triggers the bug.

28cc1aa3a7 There are some situations which can cause the URoR hack to infinitely recurse
and then go kablooie. The problem was that it was tracking the PHI nodes anew
each time into this function. But it didn't need to. And because the recursion
didn't know that a PHINode was visited before, it would go ahead and call
itself.

There is a testcase, but unfortunately it's too big to add. This problem will go
away with the EH rewrite.

5edf24efac Clean up ARM tail calls a bit. They're pseudo-instructions for normal branches.
Also more cleanly separate the ARM vs. Thumb functionality. Previously, the
encoding would be incorrect for some Thumb instructions (the indirect calls).

69a05a7b92 Generate a VTBL instruction instead of a series of loads and stores when we
can. As Nate pointed out, VTBL isn't super performant, but it *has* to be better
than this:

_shuf:
@ BB#0:       @ %entry
  push        {r4, r7, lr}
  add         r7, sp, #4
  sub         sp, #12
  mov         r4, sp
  bic         r4, r4, #7
  mov         sp, r4
  mov         r2, sp
  vmov        d16, r0, r1
  orr         r0, r2, #6

  subs        r4, r7, #4

  vst1.8      {d16[1]}, [r0]

  vldr.64     d16, [sp]
  vmov        r0, r1, d16
  mov         sp, r4
  pop         {r4, r7, pc}

The "illegal" testcase in vext.ll is no longer illegal.

b121bfcc22 Version N of the llvm_unreachable patch: VC++ doesn't recognize that abort()
doesn't return, so just go back to using the old runtime function instead
of trying to use abort() when __builtin_unreachable (or an equivalent) isn't
supported.

198e97c423 Add comment as following:
load and store reference same memory location, the memory location
is represented by getelementptr with two uses (load and store) and
the getelementptr's base is alloca with single use. At this point,
instructions from alloca to store can be removed.
(this pattern is generated when bitfield is accessed.)
For example,
%u = alloca %struct.test, align 4               ; [#uses=1]
%0 = getelementptr inbounds %struct.test* %u, i32 0, i32 0;[#uses=2]
%1 = load i8* %0, align 4                       ; [#uses=1]
%2 = and i8 %1, -16                             ; [#uses=1]
%3 = or i8 %2, 5                                ; [#uses=1]
store i8 %3, i8* %0, align 4

10a433238f Spill multiple registers at once.
Live range splitting can create a number of small live ranges containing only a
single real use. Spill these small live ranges along with the large range they
are connected to with copies. This enables memory operand folding and maximizes
the spill to fill distance.

Work in progress with known bugs.
