80db08baec Now that all the legal Neon shuffles (or at least the ones that have been 
implemented so far) are recognized during legalization, it is easy to fall
back to the default expansion for other shuffles.

d337cde6e5 Create a new ARM-specific DAG node, VDUP, to represent a splat from a 
scalar_to_vector.  Generate these VDUP nodes during legalization instead
of trying to recognize the pattern during selection.

7a311914ab During legalization, change Neon vdup_lane operations from shuffles to 
target-specific VDUPLANE nodes.  This allows the subreg handling for the
quad-register version to be done easily with Pats in the .td file, instead
of with custom code in ARMISelDAGToDAG.cpp.

dc5840c57c Update llvm-mc / MCAsmStreamer to print the instruction using the actual target 
specific printer (this only works on x86, for now).
 - This makes it possible to do some correctness checking of the parsing and
   matching, since we can compare the results of 'as' on the original input, to
   those of 'as' on the output from llvm-mc.

 - In theory, we could now have an easy ATT -> Intel syntax converter. :)

62eec42595 TargetRegistry: Reorganize AsmPrinter construction so that clients pass in the 
TargetAsmInfo. This eliminates a dependency on TargetMachine.h from
TargetRegistry.h, which technically was a layering violation.
 - Clients probably can only sensibly pass in the same TargetAsmInfo as the
   TargetMachine has, but there are only limited clients of this API.

63f93255ae Add 'isCodeGenOnly' bit to Instruction .td records. 
- Used to mark fake instructions which don't correspond to an actual machine
   instruction (or are duplicates of a real instruction). This is to be used for
   "special cases" in the .td files, which should be ignored by things like the
   assembler and disassembler. We still need a good solution to handle pervasive
   duplication, like with the Int_ instructions.

 - Set the bit on fake "mov 0" style instructions, which allows turning an
   assembler matcher warning into a hard error.

 - -2 FIXMEs.

30d9c39337 pass the TargetTriple down from each target ctor to the 
LLVMTargetMachine ctor.  It is currently unused.

40af6d5199 now that JumpTableDirective can differentate picness itself, MIPS TAI 
no longer needs a targetmachine to initialize itself.

45bdc96988 split "JumpTableDirective" (an existing hack) into a PIC and nonPIC 
version.  This allows TAI implementations to specify the directive to use
based on the mode being codegen'd for.

The real fix for this is to remove JumpTableDirective, but I don't feel
like diving into the jumptable snarl just now.
