29145a3de1 Check for EFLAGS live-out before clobbering it. 
It is only allowed to clobber EFLAGS at the end of a block if it isn't
live-in to any successor.

Tweak handling of IT blocks a bit to enable this. The differentiation between

e35fdee39e No need to get fancy inserting a PHI node when the values are stored in stack 
slots. This fixes a bug where the number of nodes coming into the PHI node may
not equal the number of predecessors. E.g., two or more landingpad instructions
may require a PHI before reaching the eh.exception and eh.selector instructions.

9cb3b3dd2e Make RecordVal Name an Init 
Store a RecordVal's name as an Init to allow class-qualified Record
members to reference Records that have Init names.  We'll use this to
provide more programmability in how we name defs and their associated
members.

36b96e4619 Enable SCEV-based unrolling by default. 
This changes loop unrolling to use the same mechanism for trip count
computation as indvars. This is a stronger check that tends to unroll
more loops. A very common side-effect is that many single iteration
loops will be removed sooner. The real goal was simply to remove
dependence on canonical IVs.

x86 is break even.
ARM performance changes to expect (+ is good):
External/SPEC/CFP2000/183.equake/183.equake +13%
SingleSource/Benchmarks/Dhrystone/fldry     +21%
MultiSource/Applications/spiff/spiff         +3%
SingleSource/Benchmarks/Stanford/Puzzle     -14%

The Puzzle regression is actually an improvement in loop optimization
that defeats GVN: rdar://problem/10065079.

316c7bfe37 Make IC_VEX* not inherit from IC_*. Prevents instructions with no VEX form from disassembling to their non-VEX form. Also prevents weak filter collisons that were keeping valid VEX instructions from decoding properly. Make VEX_L* not inherit from VEX_* because the VEX.L bit always important. This stops packed int VEX encodings from being disassembled when specified with VEX.L=1. Fixes PR10831 and PR10806.

66d5793dcf Perform the upgrading of the old EH to the new EH in a more sane manner. 
Perform the upgrading in steps.

* First, create a map of the invokes to the EH intrinsics.

* Next, take that mapping and determine if the invoke's unwind destination has a
  single predecessor. If not, then create a new empty block to hold the new
  landingpad instruction.

* Create a landingpad instruction into the uwnind destination. Fill it with the
  values from the old selector. Map the old intrinsic calls to the new
  landingpad values (there may be multiple landingpad instructions per instrinic
  call pairs).

* Go through the old intrinsic calls, create a PHI node when necessary, and then
  replace their values with the new values from the landingpad instructions.

* Delete all dead instructions.

* ???

* Profit!

6d0230847c Revert r131152, r129796, r129761. This code is currently considered 
to be unreliable on platforms which require memcpy calls, and it is
complicating broader legalize cleanups. It is hoped that these cleanups
will make memcpy byval easier to implement in the future.
