This commit adds the missing support for varargs in the instruction selection pass for AAPCS. Previously we only implemented this for Darwin. The implementation was according to AAPCS and SelectionDAG's LowerAAPCS_VASTART. It resolves all VA_START fallbacks in RAJAperf, llvm-test-suite, and SPEC CPU2017. These benchmarks now compile and pass without fallbacks due to varargs. --------- Co-authored-by: Madhur Amilkanthwar <madhura@nvidia.com>
