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.

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.

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.

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.

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.

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.
