Bob Wilson 4320e2d1bb Add the __TEXT,__StaticInit section to the list of sections emitted at the 
beginning on ARM Darwin assembly files so that it won't be placed after
debug sections.  Radar 8252813.

Chris Lattner b792b463af sink the arm implementations of ASmPrinter and MCInstLower 
out of the AsmPrinter directory into libarm.  Now the
ARM InstPrinters depend jsut on the MC stuff, not on vmcore
or codegen.

Dale Johannesen b9097a71d4 Make debug info come out in data-only files. 
This is a question of the debugging setup code not
being called at the right time, and it's called from
target-dependent code for some reason.  I have only
attempted to fix Darwin, but I'm pretty sure it's
broken elsewhere; I'll leave that to people who can
test it.

this change tickled a latent bug in Darwin's strip,

Chris Lattner a5bb370aa4 Add new shorter predicates for testing machine operands for various types: 
e.g. MO.isMBB() instead of MO.isMachineBasicBlock().  I don't plan on 
switching everything over, so new clients should just start using the 
shorter names.

Remove old long accessors, switching everything over to use the short
accessor: getMachineBasicBlock() -> getMBB(), 
getConstantPoolIndex() -> getIndex(), setMachineBasicBlock -> setMBB(), etc.

Duncan Sands 283207a71c Eliminate the remaining uses of getTypeSize. This 
should only effect x86 when using long double.  Now
12/16 bytes are output for long double globals (the
exact amount depends on the alignment).  This brings
globals in line with the rest of LLVM: the space
reserved for an object is now always the ABI size.
One tricky point is that only 10 bytes should be
output for long double if it is a field in a packed
struct, which is the reason for the additional
argument to EmitGlobalConstant.

Evan Cheng 83f35170fa - Fix codegen for pc relative constant (e.g. JT) in thumb mode: 
.set PCRELV0, (LJTI1_0_0-(LPCRELL0+4))
LPCRELL0:
        add r1, pc, #PCRELV0
This is not legal since add r1, pc, #c requires the constant be a multiple of 4.
Do the following instead:
        .set PCRELV0, (LJTI1_0_0-(LPCRELL0+4))
LPCRELL0:
        mov r1, #PCRELV0
        add r1, pc

- In thumb mode, it's not possible to use .set generate a pc relative stub
  address. The stub is ARM code which is in a different section from the thumb
  code. Load the value from a constpool instead.
- Some asm printing clean up.
