2bb4035707 Move TargetRegistry and TargetSelect from Target to Support where they belong.
These are strictly utilities for registering targets and components.

591eaa481e move PassManagerBuilder.h to IPO. This is a non intuitive place to put it,
but it solves a layering violation since things in Support are not supposed to
use things in Transforms.

bbf3b0de8b Goodbye TargetAsmInfo. This eliminate last bit of CodeGen and Target in llvm-mc.
There is still a bit more refactoring left to do in Targets. But we are now very
close to fixing all the layering issues in MC.

76792992d6 Add MCObjectFileInfo and sink the MCSections initialization code from
TargetLoweringObjectFileImpl down to MCObjectFileInfo.

2129f59637 Introduce MCCodeGenInfo, which keeps information that can affect codegen
(including compilation, assembly). Move relocation model Reloc::Model from
TargetMachine to MCCodeGenInfo so it's accessible even without TargetMachine.

d60fa58ba1 Sink getDwarfRegNum, getLLVMRegNum, getSEHRegNum from TargetRegisterInfo down
to MCRegisterInfo. Also initialize the mapping at construction time.

This patch eliminate TargetRegisterInfo from TargetAsmInfo. It's another step
towards fixing the layering violation.

fe6e405e8c Fix the ridiculous SubtargetFeatures API where it implicitly expects CPU name to
be the first encoded as the first feature. It then uses the CPU name to look up
features / scheduling itineray even though clients know full well the CPU name
being used to query these properties.

The fix is to just have the clients explictly pass the CPU name!

'ar'. Have to figure out how to make libLTO even lazier.

1e49a6d9bc Add a special streamer to libLTO that just records symbols definitions and
uses.

The result produced by the streamer is used to give the linker more accurate
information and to add to llvm.compiler.used. The second improvement removes
the need for the user to add __attribute__((used)) to functions only used in
inline asm. The first one lets us build firefox with LTO on Darwin :-)

of a base class.

the file is done. Also, this eliminates the need for

ab366f055a When handling raw_ostream errors manually, use clear_error() so that
raw_ostream doesn't try to do its own error handling.

Also, close the raw_ostream before checking for errors so that any
errors that occur during closing are caught by the manual check.

a12c1ff25a The getDefaultSubtargetFeatures method of SubtargetFeature did actually return a
string of features for that target. However LTO was using that string to pass
into the "create target machine" stuff. That stuff needed the feature string to
be in a particular form. In particular, it needed the CPU specified first and
then the attributes. If there isn't a CPU specified, it required it to be blank
-- e.g., ",+altivec". Yuck.

Modify the getDefaultSubtargetFeatures method to be a non-static member
function. For all attributes for a specific subtarget, it will add them in like
normal. It will also take a CPU string so that it can satisfy this horrible
syntax.
