Elliott Hughes 7dd3896fe1 riscv64: switch from x18 to gp for shadow call stack. ... We want to give back a useful callee-saved general purpose register (x18) that was only "chosen" because it was what llvm allowed for historical reasons. gp is a better choice because it's effectively unused otherwise anyway. Unfortunately, that means we need extra space in jmp_buf (which I've reserved in an earlier change, e7b3b8b467), so let's rearrange the entries in jmp_buf to match their order in the register file.
