4bdaace06e improve the APIs for creating struct and function types with no arguments/elements
to not have to create a temporary vector (in the API at least).  Patch by Jay Foad!

37503e9671 Handle IMPLICIT_DEF with isUndef operand marker, part 2. This patch moves the code to annotate machineoperands to LiveIntervalAnalysis. It also add markers for implicit_def that define physical registers. The rest, is just a lot of details.

bc3d149e98 Remove unused AsmPrinter OptLevel argument, and propogate.
- This more or less amounts to a revert of r65379. I'm curious to know what
   happened that caused this variable to become unused.

d0589c59b3 llvm-mc: Symbols in a relocatable expression of the (a - b + cst) form are
allowed to be undefined when the expression is seen, we cannot enforce the
same-section requirement until the entire assembly file has been seen.

c0fb316bd3 Add an "alignment" field to the MachineFunction object. It makes more sense to
have the alignment be calculated up front, and have the back-ends obey whatever
alignment is decided upon.

This allows for future work that would allow for precise no-op placement and the
like.

Avoid unnecessary duplication of operand 0 of X86::FpSET_ST0_80. This duplication would
cause one register to remain on the stack at the function return.

28b9e77f19 Temporarily restore the scavenger implicit_def checking code. MachineOperand isUndef mark is not being put on implicit_def of physical registers (created for parameter passing, etc.).

c6c942b70f Add a bit IsUndef to MachineOperand. This indicates the def / use register operand is defined by an implicit_def. That means it can def / use any register and passes (e.g. register scavenger) can feel free to ignore them.
The register allocator, when it allocates a register to a virtual register defined by an implicit_def, can allocate any physical register without worrying about overlapping live ranges. It should mark all of operands of the said virtual register so later passes will do the right thing.

This is not the best solution. But it should be a lot less fragile to having the scavenger try to track what is defined by implicit_def.
