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.

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.

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. :)

When standard output is a terminal, set outs() to be unbuffered, to
mimic the behavior of stdtout, which is line-buffered when the output

Take the fast path for any named value and any GlobalValue, which doesn't

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.

Set raw_os_ostream, raw_string_ostream, and raw_svector_ostream to be
unbuffered. std::ostream does its own buffering, and std::string and
SmallVector both have allocation strategies intended to handle frequent
appending.

Add support to raw_ostream for sizing the buffer according to the

constructing a TypePrinting object and populating it with strings for all
the numbered types in the Module on each call is a significant bottleneck.
Fancier solutions could be pursued here, but for now, just bypass the
TypePrinting overhead in obvious cases.

Change the indentation for LLVM Assembly files from 1 tab to 2 spaces.
This is vaguely consistent with LLVM's own source code, but more
importantly it lets more lines stay within 80 columns.

Now that numbered types have their number printed, it's no longer
interesting to print the number in a comment. Numbered instructions
don't need their number in a comment either.

Also, tidy up newline printing.

Add a new "SDTCisVec" SDTypeConstraint.  This complements the vAny type.
There have been a few times where I've wanted this but ended up leaving the
