The TableGen-based calling convention definitions are inflexible, while writing a function to implement the calling convention is very straight-forward, and allows difficult cases to be handled more easily. With this patch adds support for: * Passing large scalars according to the RV32I calling convention * Byval arguments * Passing values on the stack when the argument registers are exhausted The custom CC_RISCV calling convention is also used for returns. This patch also documents the ABI lowering that a language frontend is expected to perform. I would like to work to simplify these requirements over time, but this will require further discussion within the LLVM community. We add PendingArgFlags CCState, as a companion to PendingLocs. The PendingLocs vector is used by a number of backends to handle arguments that are split during legalisation. However CCValAssign doesn't keep track of the original argument alignment. Therefore, add a PendingArgFlags vector which can be used to keep track of the ISD::ArgFlagsTy for every value added to PendingLocs.
