as well as the StringRef change.

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.

ed9c7f2749 CMake: updated list of source files for library MC.

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. :)

0c10b8864a When standard output is a terminal, set outs() to be unbuffered, to 
mimic the behavior of stdtout, which is line-buffered when the output
is a terminal. This fixes some issues with bugpoint output appearing
being printed out of order.

4d57894a63 Take the fast path for any named value and any GlobalValue, which doesn't 
need TypePrinting despite being a subclass of Constant. This fixes
compile-time problems especially visible on 403.gcc when -asm-verbose is
enabled.

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.

c692477e5e 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.

4ac7200d66 Add support to raw_ostream for sizing the buffer according to the

st_blksize from fstat to determine a buffer size.
