088880cb19 Change allowsUnalignedMemoryAccesses to take type argument since some targets 
support unaligned mem access only for certain types. (Should it be size
instead?)

ARM v7 supports unaligned access for i16 and i32, some v6 variants support it
as well.

7d996d907f 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.

72977a45a8 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!

9a0b165cb5 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.

c22e0b2443 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. :)

67d894ea64 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.
