6ff3fd8021 Remove TPat. No patterns depend on just isThumb(). Must use either T1Pat (isThumb1Only()) or T2Pat (is Thumb2).

a773ae7a39 Get rid of some more getOpcode calls. 
This also fixes potential problems in ARMBaseInstrInfo routines not recognizing thumb1 instructions when 32-bit and 16-bit instructions mix.

793cbcd529 sink text/data section creation down into the target-specific places that 
should know about them.  PECoff doesn't share these, and I want all sections
to be created by object-file-specific code.

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.

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.

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.
