39284d191a Never delete instructions that define reserved registers.
I think this was already the intention, but DeadMachineInstructionElim
was accidentally tracking the liveness of reserved registers. Now,
instructions with reserved defs are never deleted.

This prevents the call stack adjustment instructions from getting
deleted when enabling register masks.

a8fc171b3f Handle register masks in MachineCopyPropagation.
For simplicity, treat calls with register masks as basic block
boundaries.  This means we can't copy propagate callee-saved registers
across calls, but I don't think that is a big deal.

1dd8c8560d Codegen pass definition cleanup. No functionality.
Moving toward a uniform style of pass definition to allow easier target configuration.
Globally declare Pass ID.
Globally declare pass initializer.
Use INITIALIZE_PASS consistently.
Add a call to the initializer from CodeGen.cpp.
Remove redundant "createPass" functions and "getPassName" methods.

While cleaning up declarations, cleaned up comments (sorry for large diff).

instead of using a large switch statement.

3fd3a840c5 Keep track of register masks in LiveIntervalAnalysis.
Build an ordered vector of register mask operands (i.e., calls) when
computing live intervals. Provide a checkRegMaskInterference() function
that computes a bit mask of usable registers for a live range.

This is a quick way of determining of a live range crosses any calls,
and restricting it to the callee saved registers if it does.
Previously, we had to discover call clobbers for each candidate register
independently.

I added the full testing for all possible pseudo-ops of cmp.
I extended X86AsmPrinter.cpp and X86IntelInstPrinter.cpp.

You'l also see lines alignments (unrelated to this fix) in X86IselLowering.cpp from my previous check-in.

4871701437 No actual functional change here, just some clarifications:
Clarify that contributors are agreeing to license their code under the 
license corresponding to the subproject that they are contributing to,
as requested by a potential contributor.

Also, as a drive-by, update the llvm-gcc/GPL section to mention dragonegg
and say that GPL code is all in its own repo's.
