Create Generic DOTGraphTraits Printer/Viewer

Move the DOTGraphTraits dotty printer/viewer templates, that were developed for
the dominance tree into their own header file. This will allow reuse in future
passes.

Remove DEBUG_DECLARE, looks like we don't need it.
Also, DEBUG_VALUE has side effects.

Fix cmp emission on msp430: we definitely should turn stuff like
"icmp lhs, rhs" into "cmp rhs, lhs". This should fix PR5979.

Do not use AT_specification die for static variables. It confuses gdb.

EmitAtomicCmpSwap() custome inserter needs to delete the MI passed in. EmitAtomicBinary() already does this.

Added 16-bit Thumb Load/Store immediate instructions with encoding bits so that
the disassembler can properly decode Load/Store register/immediate instructions.

add virtual methods to get the start/end of a MCParsedAsmOperand,
the default implementation returns "unknown".

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@93470 91177308-0d34-0410-b5e6-96231b3b80d8

Split the TargetAsmParser "ParseInstruction" interface in half:
the new ParseInstruction method just parses and returns a list of
target operands.  A new MatchInstruction interface is used to
turn the operand list into an MCInst.

This requires new/deleting all the operands, but it also gives
targets the ability to use polymorphic operands if they want to.

Dwarf EH prepare needs to be run after SjLj prepare. Otherwise,
catch info can get misplaced when a selector ends up more than one block
removed from the parent invoke(s). This could happen when a landing pad is
shared by multiple invokes and is also a target of a normal edge from
elsewhere.
