39c0d3b10a Change the assembly syntax for nsw, nuw, and exact, putting them 
after their associated opcodes rather than before. This makes them
a little easier to read.

c1b29cb551 fixed incorrect lowering of ISD::SUB node. SUB has only one result value. 
It wasn't caught during tests because we never got a sub generated, (i8 was always getting promoted to int, which in turn was broken into subc/sube). Though the optimizer leaves an i8 sub now.

a6737e21cf Rename tMOVhi2lor to tMOVgpr2tgpr. It's not moving from a high register to a low register. It's moving from a GPR register class to a more restrictive tGPR class. Also change tMOVlor2hir, and tMOVhir2hir.

4e4475ce49 Fix libLTO: 
* Call InitializeAllTargets on every path where we might query the
   TargetRegistry. This fixes PR4604.
 * flush the formatted_raw_ostream& or else not all of the assembly will make
   it to the .s file. (It doesn't do this in its destructor?!)
 * Due to a reversed conditional, libLTO was reporting many symbols as both
   defined and undefined, including two definitions of the same symbol name
   in its symbol list.

0f4d60ca90 untangle a TargetAsmInfo hack where ELFTargetAsmInfo would create a 
'unnamed' bss section, but some impls would want a named one.  Since
they don't have consistent behavior, just make each target do their
own thing, instead of doing something "sortof common" then having
targets change immutable objects later.

8e840e942e Use the RHS length instead of the LHS length. They are both the same, 
but this ends up compiling code like this:

int foo(const StringRef &R) {
  return R == "food";
}

to use a constant sized memcmp instead of a variable memcmp.

c130e8eae9 Move MSILModule and MSILWriter into the 'llvm' namespace, instead of the 'MSIL' 
namespace which could very well conflict with non-LLVM code.

Also clean up some spacing, remove an extra header.

b3d6d59c10 Rearrange all the SectionKinds and structure them into a hierarchical 
group instead of a bunch of random unrelated ideas.  Provide predicates
to categorize a SectionKind into a group, and use them instead of 
getKind() throughout the code.

This also renames a ton of SectionKinds to be more consistent and
evocative, and adds a huge number of comments on the enums so that
I will hopefully be able to remember how this stuff works long from
now.
