Update the RISC-V calling conventions (#221)
We were implementing the ABI described in the RISC-V Instruction Set
Manual, version 2.1. However, this ABI was superseded by the RISC-V
ELF psABI specification.
This commit changes the calling conventions to better match the ELF psABI
specification. This should greatly improve interoperability with code
compiled by other RISC-V compilers.
One incompatibility remains: when all 8 FP argument registers have been used, further FP arguments should be passed in integer argument registers if available, while this PR passes them on stack.
