We need to find a better way to emit this info.

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

the disassembler can properly decode Load/Store register/immediate instructions.

the default implementation returns "unknown".

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.

Pass in SMLoc of instr opcode into ParseInstruction.
Make AsmToken be a class, not a struct.

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.

Avoid modifying ValueEnumerator's MD ValueList by choosing which function-local MD to write based on the function currently being written

This is consistent with llvm-gcc's arm/constraints.md.

Certain instructions (e.g. CBZ, CBNZ) require a low register, even in Thumb2
mode.

Now that LLParser, AsmWriter, BitcodeReader, and BitcodeWriter all correctly support function-local metadata, test it.

llvm-svn: 93406

In WriteFunction(), write function-local metadata before we write the instructions, so instruction's references to metadata are fully resolved by the time they get written.

Add MDNode::getFunction(), which figures out the metadata's function, if it has function that it is local to.

An unaligned ldr causes a trap, and is then emulated by the kernel with
awesome performance. The darwin kernel does not emulate unaligned ldm/stm
Thumb2 instructions, so don't generate them.

This fixes the miscompilation of Multisource/Applications/JM/lencod for Thumb2.

Generating unaligned ldr/str pairs from a 16-bit aligned memcpy is probably
also a bad idea, but that is beyond the scope of this patch.
