c799065cc3 Add a quick and dirty "loop aligner pass". x86 uses it to align its loops to 16-byte boundaries.

c24ea4fb41 Change "Name" to "AsmName" in the target register info. Gee, a refactoring tool 
would have been a Godsend here!

6ca3ccf519 Rewrite tblgen handling of subtarget features so 
it follows the order of the enum, not alphabetical.
The motivation is to make -mattr=+ssse3,+sse41
select SSE41 as it ought to.  Added "ignored"
enum values of 0 to PPC and SPU to avoid compiler
warnings.

1a17ef02c8 If there's no instructions being emitted on X86 for a function, emit a 
nop. Emit the nop directly for PPC.

5079483957 If there are no machine instructions emitted for a function, then insert 
a "nop" instruction so that we don't have the function's label associated
with something that it's not supposed to be associated with.

60a9855799 Revert the part of 45848 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.

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.

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.
