3665e2058e add support for target-specific ELF section flags, add a new MCSectionXCore 
class which represents the XCore cp/dp section flags.  No functionality
change yet.

the pred list instead of a vector, saving a boat load of malloc/free's.

d69323d37a On x86-64, for a varargs function, don't store the xmm registers to 
the register save area if %al is 0. This avoids touching xmm
regsiters when they aren't actually used.

3a0cde8c91 Allow targets to specify their choice of calling conventions per 
libcall. Take advantage of this in the ARM backend to rectify broken
choice of CC when hard float is in effect. PIC16 may want to see if
it could be of use in MakePIC16Libcall, which works unchanged.

Patch by Sandeep!

3c9ab92a24 llvm-mc: Fix bugs where bytes were unintentionally being printed as signed. 
- We now print all of 403.gcc cleanly (llvm-mc -> 'as' as diffed to 'as'), minus two 
   'rep;movsl' instructions (which I missed before).

b9d9ce9513 llvm-mc: When handling a .set, make sure to print subsequent references to the 
symbol as the symbol name itself, not the expression it was defined to. These
have different semantics due to the quirky .set behavior (which absolutizes an
expression that would otherwise be treated as a relocation).

e8ee71bbd8 Revert r78424. 
In order for the changes in r78424 to work properly, cast_retty<X,Y> should return an object instead of a reference, and it's not clear that this approach has real advantages.

fc64077eb6 CMake: Automatic regeneration of the library dependencies file. 
It doesn't stop or reconfigure the build, though, so the user will see
a broken build that magically succeeds at the next attempt. It is
technically possible to halt the build with a helpful message, and
even to automatically restart the build using the new dependencies as
it we did when llvm-config was used by cmake for learning
dependencies. This is left on the TODO list.

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. :)
