7739cad69d Add a new kind of MachineOperand: MO_RegisterMask.
Register masks will be used as a compact representation of large clobber
lists.  Currently, an x86 call instruction has some 40 operands
representing call-clobbered registers.  That's more than 1kB of useless
operands per call site.

A register mask operand references a bit mask of call-preserved
registers, everything else is clobbered.  The bit mask will typically
come from TargetRegisterInfo::getCallPreservedMask().

By abandoning ImplicitDefs for call-clobbered registers, it also becomes
possible to share call instruction descriptions between calling
conventions, and we can get rid of the WINCALL* instructions.

This patch introduces the new operand kind.  Future patches will add
RegMask support to target-independent passes before finally the fixed
clobber lists can be removed from call instruction descriptions.

9d9c4ad186 According to Mips folks, the backend is now generally reliable (they can
compile and use a bunch of stuff using o32 abi). Also the rt-rk.com team
claims that the JIT support they contributed, is complete for the mips
"static" relocation model.
