Fix a serious performance regression introduced by r108687 on linux:
turning (fptrunc (sqrt (fpext x))) -> (sqrtf x)  is great, but we have
to delete the original sqrt as well.  Not doing so causes us to do 
two sqrt's when building with -fmath-errno (the default on linux).

Dan Gohman 46ffb231c6 Disable the asserts that check that normalization is perfectly

in canonicalizing equal expressions to a single canonical form, and
this can cause these asserts to fail, even though there's no actual
correctness problem. This fixes PR8066.

Owen Anderson 1593dd6779 Add support for simplifying a load from a computed value to a load from a global when it 
is provable that they're equivalent.  This fixes PR4855.

Jim Grosbach 65482b1bb8 Re-apply r112883: 
"For ARM stack frames that utilize variable sized objects and have either
large local stack areas or require dynamic stack realignment, allocate a
base register via which to access the local frame. This allows efficient
access to frame indices not accessible via the FP (either due to being out
of range or due to dynamic realignment) or the SP (due to variable sized
object allocation). In particular, this greatly improves efficiency of access
to spill slots in Thumb functions which contain VLAs."

r112986 fixed a latent bug exposed by the above.

Jakob Stoklund Olesen 1e3aeefc08 VirtRegRewriter checks for early clobbers before it reuses an available stack 
slot.

Teach it to also check for early clobbered aliases, and early clobber operands
following the current operand.

This fixes the miscompilation in PR8044 where EC registers eax and ecx were
being used for inputs.

Jim Grosbach fc63300233 Check the local frame alignment for determining whether dynamic stack 
alignment should be performed. Otherwise dynamic realignment may trigger
when the register allocator has already used the frame pointer as a general
purpose register. That is, we need to make sure that the list of reserved
registers doesn't change after register allocation.

Bob Wilson f572191fe4 Finish converting the rest of the NEON VLD instructions to use pseudo- 
instructions prior to regalloc.  Since it's getting a little close to
the 2.8 branch deadline, I'll have to leave the rest of the instructions
handled by the NEONPreAllocPass for now, but I didn't want to leave half
of the VLD instructions converted and the other half not.
