Fix a number of encoding bugs. SSE 4.1 instructions MPSADBWrri, PINSRDrr, etc. have 8-bits immediate field (ImmT == Imm8).

the type instead of the byte size. This was causing troublesome mis-compilations.

True to form, this took 2 days to find and is a one-line fix. :-P

Use getIntPtrConstant in a couple places to shorten stuff up
Handle splitting vector shuffles with undefs in the mask

An address space name cannot be used to qualify an object that has automatic
storage duration.  Still not catching ASQual'd allocas of array type, just 
scalars at the moment.

Livein copy scheduling fixes: do not coalesce physical register copies, correctly determine the safe location to insert the copies.

Don't try to sink 3-address instruction if convertToThreeAddress created more than one instructions.

TwoAddressInstructionPass enhancement. After it converts a two address instruction into a 3-address one, sink it past the instruction that kills the read-mod-write register if its definition is used past the kill. This reduces the number of live register by one.

This still isn't right, but is slightly nicer.

Set the start of DeclStmt range.  Right now the end is meaningless 
though.

Get rid of a pseudo instruction and replace it with subreg based operation on real instructions, ridding the asm printers of the hack used to do this previously. In the process, update LowerSubregs to be careful about eliminating copies that have side affects. 

Note: the coalescer will have to be careful about this too, when it starts coalescing insert_subreg nodes.

we gracefully back out and return NULL for the CFG, allowing clients to skip
analyzing functions with these CFGs. We will add support later.

Modified base ASTConsumer "CFGVisitor" to detect when a CFG is not constructed
and to emit a warning.
