argument to runJITOnFunction(), which caused a null pointer dereference at
every call.

was using "Tmp1" in the first getNode call instead of Node->getOperand(0).

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.

ARM uses these to indicate predicates.

Made LEA memory operands emit only 4 MCInst operands.
Made the scale operand equal 1 for instructions that have no
SIB byte.

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

"indirect" operand is not a pointer.

Remove target attribute break-sse-dep. Instead, do not fold load into sse partial update instructions unless optimizing for size.

While converting one of the operands to a memory operand, we need to check if it is Legal and does not result into a cyclic dep.

missing check that an array reference doesn't go past the end of the array,
and remove some redundant checks for in-bound array and vector references
that are no longer needed.

to not produce caret diagnostics, you were right!

currently likes to duplicate the return (an unfortunate choice!)

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.

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