Sooooo many of these had incorrect or strange main module includes.
I have manually inspected all of these, and fixed the main module
include to be the nearest plausible thing I could find. If you own or
care about any of these source files, I encourage you to take some time
and check that these edits were sensible. I can't have broken anything
(I strictly added headers, and reordered them, never removed), but they
may not be the headers you'd really like to identify as containing the
API being implemented.

Many forward declarations and missing includes were added to a header
files to allow them to parse cleanly when included first. The main
module rule does in fact have its merits. =]

of several newly un-defaulted switches. This also helps optimizers
(including LLVM's) recognize that every case is covered, and we should
assume as much.

change, now you need a TargetOptions object to create a TargetMachine. Clang
patch to follow.

One small functionality change in PTX. PTX had commented out the machine
verifier parts in their copy of printAndVerify. That now calls the version in
LLVMTargetMachine. Users of PTX who need verification disabled should rely on
not passing the command-line flag to enable it.

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.

llvm-svn: 135611

TargetLoweringObjectFileImpl down to MCObjectFileInfo.

TargetAsmInfo is done to one last method. It's *almost* gone!

supports compact unwind info instead of having a separate flag indicating this.

If the linker supports it, this will hold the CIE and FDE information in a
compact format. The implementation of the compact unwinding emission is coming
soon.

other targets left this flag "false".

give it a bit more responsibility. Also implement it for MachO.

If hacked to use cfi, 32 bit MachO will produce

.cfi_personality 155, L___gxx_personality_v0$non_lazy_ptr

and 64 bit will produce

.cfi_presonality ___gxx_personality_v0

The general idea is that .cfi_personality gets passed the final symbol. It is
up to codegen to produce it if using indirect representation (like 32 bit
MachO), but it is up to MC to decide which relocations to create.

  error in foo.o; no .eh_frame_hdr table will be created.

Change ELF systems to use CFI for producing the EH tables. This reduces the
size of the clang binary in Debug builds from 690MB to 679MB.

It broke several builds.

readonly section, just not a mergable one.

support aligned comm.  Detect when compiling for 10.4 and don't
emit an alignment for comm.  THis will hopefully fix PR8198.

just make unnamed temp symbols instead of having to come
up with its own names.

where we used ot create an MCSymbol for ".".  Now emit an assembler
temporary label and reference it instead of "." textually.

an MCExpr and not an MCSymbol.  Change it to take an MCStreamer,
which is currently unused.

No functionality change.

darwin/x86[-64]!
