[PATCH] D27051: Propagate NumRegisterParameters to Backend

[Michael Kuperstein via llvm-commits]

Another issue is that we need to serialize this as part of the IR for the function.
Since we don't use inreg attributes, it needs to either be a part of the calling convention (although we currently have no way to parametrize the CC, I think), or a function attribute.
