d7e8bd73fe completely eliminate the MOV16r0 'instruction'. The only 
interesting part of this is the divrem changes, which are
already tested by CodeGen/X86/divrem.ll.

dbcf2725aa stop pattern matching 16-bit zero's of a register to MOV16r0, 
instead use the appropriate subreggy thing.  This generates identical
code on some large apps (thanks to Evan's cross class coalescing
stuff he did back in july).  This means that MOV16r0 can go away
completely in the future soon.

0c46d96fd0 Partially revert r91626. Materializing extra functions to determine whether 
they're available_externally broke VMKit, which was relying on the fact that
functions would only be materialized when they were first called.  We'll have
to wait for http://llvm.org/PR5737 to really fix this.

I also added a test for one of the F->isDeclaration() calls which wasn't
covered by anything else in the test suite.

47b4d6387f Remove minimal CFG sanity checks from verifier. 
These checks would often trigger on unreachable statements inserted by
bugpoint, leading it astray.

It would be nice if we could distinguish unreachable blocks from errors.

4a7bce50b8 Fix the Convert to scalar to not insert dead loads in the store case. The 
load is needed when we have a small store into a large alloca (at which 
point we get a load/insert/store sequence), but when you do a full-sized
store, this load ends up being dead.

This dead load is bad in really large nasty testcases where the load ends
up causing mem2reg to insert large chains of dependent phi nodes which only
ADCE can delete.  Instead of doing this, just don't insert the dead load.

This fixes rdar://6864035

0dc93264b1 Generalize SROA to allow the first index of a GEP to be non-zero. Add a

that are no longer needed.

by merging all returns in a function into a single one, but simplifycfg

cd79ebb23c The phi translated pointer can be computed when returning a partially cached result 
instead of stored.  This reduces memdep memory usage, and also eliminates a bunch of
weakvh's.  This speeds up gvn on gcc.c-torture/20001226-1.c from 23.9s to 8.45s (2.8x)
on a different machine than earlier.

fc4c238bd5 Add more plumbing. This time in the LowerArguments and "get" functions which 
return partial registers. This affected the back-end lowering code some.

Also patch up some places I missed before in the "get" functions.
