When we switch to opaque pointer types we will need some way to describe how many bytes a 'byval' parameter should occupy on the stack. This adds a (for now) optional extra type parameter. If present, the type must match the pointee type of the argument. The original commit did not remap byval types when linking modules, which broke LTO. This version fixes that. Note to front-end maintainers: if this causes test failures, it's probably because the "byval" attribute is printed after attributes without any parameter after this change. llvm-svn: 362128
