MachineLoopInfo.
llc now runs MachineLoopInfo and MachineDominatorTree only twice, instead
of three times.

instructions for calls since BL and BLX are always 32-bit long and BX is always
16-bit long.
Also, we should be using BLX to call external function stubs.

in SelectionDAGLowering::visitTargetIntrinsic.
This removes a bit of special-case code for vector types. After staring
at it for a while, I managed to convince myself that it is not necessary.
The only case where TLI.getValueType() differs from MVT::getMVT is for iPTR,
so this code could potentially make a difference for a vector of pointers.
But, it looks like that is not supported. Calling TLI.getValueType() on
a vector of pointers leads to the following sequence of calls:
TargetLowering::getValueType
MVT::getMVT
MVT::getVectorVT(iPTR, num elements)
MVT::getExtendedVectorVT
MVT::getTypeForMVT for iPTR
assertion fails "Type is not extended!"
So, unless I'm really missing something, this bit of code is irrelevant to
the current version of LLVM, which is consistent with the fact that I don't
see this code in other similar places.

- Operands which are just a label should be parsed as immediates, not memory
operands (from the assembler perspective).
- Match a few more flavors of immediates.
- Distinguish match functions for memory operands which don't take a segment
register.
- We match the .s for "hello world" now!

padding is disabled, tabs get replaced by spaces except in the case of
the first operand, where the tab is output to line up the operands after
the mnemonics.
Add some better comments and eliminate redundant code.
Fix some testcases to not assume tabs.

because it just calls the default impl.
Remove the PPCDarwinTargetAsmInfo version of PreferredEHDataFormat because
it just returns DW_EH_PE_absptr unless on 10.6. However, 10.6 doesn't support
PPC, so the default impl is just fine.
