StackMap: FastISel: Add an appropriate number of immediate operands to the frame setup instruction. This commit ensures that the stack map lowering code in FastISel adds an appropriate number of immediate operands to the frame setup instruction. The previous code added just one immediate operand, which was fine for a target like AArch64, but on X86 the ADJCALLSTACKDOWN64 instruction needs two explicit operands. This caused the machine verifier to report an error when the old code added just one. Reviewers: Juergen Ributzka Differential Revision: http://reviews.llvm.org/D11853 llvm-svn: 244508
