[libre-riscv-dev] rust llvm intrinsic vector support

[Luke Kenneth Casson Leighton]

hi jacob,

occurred to me that it might be a good idea to reach out to the rust
dev team to see whether they're happy to put vectorisation support
into llvm.  that does mean there's a dependency of actually having the
variable-length vector intrinsic in the llvm front-end.  must also
ping alex bradbury and the other person about that.
