* 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.

'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.

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.

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.
