The code pattern "imm0_255_neg" is used for checking if an immediate value is a small negative number.
This patch changes the definition of negative from -0..-255 to -1..-255. I am changing this because of
a bug that we had in some of the patterns that assumed that "subs" of zero does not set the carry flag.

Patch by Logan Chien with some cleanups from me.

Iterating over the children of each node in the potential vectorization
plan must happen in a deterministic order (because it affects which children
are erased when two children conflict). There was no need for this data
structure to be a map in the first place, so replacing it with a vector
is a small change.

I believe that this was the last remaining instance if iterating over the
elements of a Dense* container where the iteration order could matter.
There are some remaining iterations over std::*map containers where the order
might matter, but so long as the Value* for instructions in a block increase
with the order of the instructions in the block (or decrease) monotonically,
then this will appear to be deterministic.

When an instruction as written requires 32-bit mode and we're assembling
in 64-bit mode, or vice-versa, issue a more specific diagnostic about
what's wrong.

This seems like redundant leftovers from r142288 - exposing
TargetData::parseSpecifier to LLParser - which got reverted. Removes
redunant td != NULL checks in parseSpecifier, and simplifies the
interface to parseSpecifier and init.

Assignment of Bitcode ownership to Joe Abbey, after announcing proposal on
LLVMdev and not hearing any major objections.  Although it did spark a nice
