Implementation is NOT compatible with IBM XL C 16.1 and earlier but is compatible with GCC. It handles all ByVals with greater alignment then pointer width the same way IBM XL C handles Byvals that have vector members. For overaligned objects that do not contain vectors IBM XL C does not align them properly if they are passed in the GPR argument registers. This patch was originally written by Sean Fertile @mandlebug. Previously on Phabricator https://reviews.llvm.org/D105659
