Rename CodeGenFunction::EmitMemSetToZero to EmitNullInitialization. Handle setting null data member pointers correctly. Fixes PR7139.

that are aliases of the specified register.
- Rename modifiesRegister to definesRegister since it's looking a def of the
specific register or one of its super-registers. It's not looking for def of a
sub-register or alias that could change the specified register.
- Added modifiesRegister to look for defs of aliases.

This takes partial redefines and undef uses into account.

Don't actually use it yet. That caused miscompiles.

If someone knows how to write a useful test for this, I'd be grateful. 

llvm-svn: 104335

If the size of the string is greater than the zero fill size, the function will attempt to write a very large string of zeros to the object file (~4GB on 32 bit platforms). This assertion will catch the scenario and crash the program before the write occurs.

pass after isel instead of being interlaced with it, we can
trust that all the code for a function has been isel'd before
it is run.

The practical impact of this is that we can scan for machine
instr phis instead of doing a fuzzy match on the LLVM BB for
phi nodes.  Doing the fuzzy match required knowing when isel
would produce an fp reg stack phi which was gross.  It was
also wrong in cases where select got lowered to a branch
tree because cmovs aren't available (PR6828).

Just do the scan on machine phis which is simpler, faster
and more correct.  This fixes PR6828.

definitions of the virtual register.

This happens when spilling the registers produced by REG_SEQUENCE:

%reg1047:5<def>, %reg1047:6<def>, %reg1047:7<def> = VLD3d8 %reg1033, 0, pred:14, pred:%reg0

The rewriter would spill the register multiple times, dead store elimination
tried to keep up, but ended up cutting the branch it was sitting on.
