6fa384f4a7 centralize "marking for deletion" into a helper function. Pass GVN around to 
static functions instead of passing around tons of random ivars.

bb0599c1f4 Fix the last -Wnon-pod-memset I'm seeing. This is benign, but appears 
a bit more sinister as the memset doesn't do what the constructor does.
There seems to be a cleaner solution than a cast here though, instead we
can point the memset destination into the union its actually trying to
clear.

An alternative is to point to the Untyped member of this union. Review
appreciated, and if that is cleaner I'm happy to switch. All of these
should be functionally equivalent to the original code.

594c4c5823 teach GVN to widen integer loads when they are overaligned, when doing an 
wider load would allow elimination of subsequent loads, and when the wider
load is still a native integer type.  This eliminates a ton of loads on 
various benchmarks involving struct fields, though it is somewhat hobbled
by clang not being very aggressive about field alignment.

This is yet another step along the way towards resolving PR6627.

0525497a16 Rename getPersonalityPICSymbol to getCFIPersonalitySymbol, document it, and 
give it a bit more responsibility. Also implement it for MachO.

If hacked to use cfi, 32 bit MachO will produce

.cfi_personality 155, L___gxx_personality_v0$non_lazy_ptr

and 64 bit will produce

.cfi_presonality ___gxx_personality_v0

The general idea is that .cfi_personality gets passed the final symbol. It is
up to codegen to produce it if using indirect representation (like 32 bit
MachO), but it is up to MC to decide which relocations to create.

652ca6a95a Fixes PR9730: indvars: An asserting value handle still pointed to this value 
Modified LinearFunctionTestReplace to push the condition on the dead
list instead of eagerly deleting it. This can cause unnecessary
IV rewrites, which should have no effect on codegen and will not be an
issue once we stop generating canonical IVs.

fa34d31aa4 If converter was being too cute. It look for root BBs (which don't have 
successors) and use inverse depth first search to traverse the BBs. However
that doesn't work when the CFG has infinite loops. Simply do a linear
traversal of all BBs work just fine.

4c4f3dbea6 Stop trying to have instcombine preserve LCSSA form: this was not 
effective in avoiding recomputation of LCSSA form; the widespread
use of instsimplify (which looks through phi nodes) means it was
not preserving LCSSA form anyway; and instcombine is no longer
scheduled in the middle of the loop passes so this doesn't matter
anymore.
