14b93851cc add simple support for addrmode5 operands, allowing
vldr.64 to work.  I have no idea if this is fully right, but 
it is in the right direction.

e73d4f8ec7 give better error diagnostics, for example:
t.s:1:14: error: invalid operand for instruction
vldr.64	d17, [r0]   
       	     ^

instead of:

t.s:1:1: error: unrecognized instruction
vldr.64	d17, [r0]   
^

6274ec48b3 hook up getOpcodeName for ARM so that "llc -show-mc-inst" includes
the opcode string in the inst dump, e.g.:
	vmov	r2, r3, d17             @ encoding: [0x31,0x2b,0x53,0xec]
                                        @ <MCInst #989 VMOVRRD

The "VMOVRRD" is new.

f4b0f3e616 Improvements to .section parsing:
* If we have a M or a G, reject sections without the type
* Only parse the flag specific arguments if we have M or G
* Parse the corresponding arguments for M and G

We ignore the G arguments and flag for now.

e1dde7b05a Replace SplitKit SSA update with an iterative algorithm very similar to the one
in SSAUpdaterImpl.h

Verifying live intervals revealed that the old method was completely wrong, and
we need an iterative approach to calculating PHI placemant. Fortunately, we have
MachineDominators available, so we don't have to compute that over and over
like SSAUpdaterImpl.h must.

Live-out values are cached between calls to mapValue() and computed in a greedy
way, so most calls will be working with very small block sets.

Thanks to Bob for explaining how this should work.

d68f458244 Make MachineDominators available for SplitEditor. We are going to need it for
proper SSA updating.

This doesn't cause MachineDominators to be recomputed since we are already
requiring MachineLoopInfo which uses dominators as well.

24a492683c Revert r117582, which reverted r77396. Searching PATH for a string
which contains slashes is inconsistent with the meaning of PATH on
Unix-type platforms, and pretty surprising.

If the user has given a specific path to execute and we can't
execute it, we should fail and say why.  (Apparently the new
posix_spawn code doesn't always say why, but that's a separate
issue.)

c61c7549a8 Revert r77396.
Original commit message:

    On "Unix", if Program::FindProgramByName is given a name containing
    slashes, just go with it, regardless of whether it looks like it will
    be executable. This follows the behavior of sh(1) more closely.

It's better when behaviour is consistent between platforms. This change also
makes FindExecutable() behave as expected on unix-likes (before this commit, it
used to always succeed).

0104d9de04 - Assign load / store with shifter op address modes the right itinerary classes.
- For now, loads of [r, r] addressing mode is the same as the
  [r, r lsl/lsr/asr #] variants. ARMBaseInstrInfo::getOperandLatency() should
  identify the former case and reduce the output latency by 1.
- Also identify [r, r << 2] case. This special form of shifter addressing mode
  is "free".
