5d841097a9 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.

class which represents the XCore cp/dp section flags.  No functionality
change yet.

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!

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.

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.

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.

st_blksize from fstat to determine a buffer size.
