fb8075d03f Add a quick and dirty "loop aligner pass". x86 uses it to align its loops to 16-byte boundaries.

74ab84c31e Change "Name" to "AsmName" in the target register info. Gee, a refactoring tool
would have been a Godsend here!

3006c39e3a __DATA not __DATA__ is the right segment name on darwin.

25a0195114 Revert the part of 45849 that treated weak globals
as weak globals rather than commons.  While not wrong,
this change tickled a latent bug in Darwin's strip,
so revert it for now as a workaround.

8aa797aa51 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.

ca0ed74485 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.

c60e76d139 - 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.
