Patch adds support for passing vector call operands to variadic functions. Arguments which are fixed shadow GPRs and stack space even when they are passed in vector registers, while arguments passed through ellipses are  passed in(properly aligned GPRs if available and on the stack once all GPR arguments registers are consumed.
