[PATCH] D46423: [WIP, RISCV] Support .option relax and .option norelax

[Lewis Revill via Phabricator via llvm-commits]

Well apologies for the noise and the late update, but it looks like we can't have an early `.option norelax` overriding the behaviour specified with `mattr=+relax`. This is because the lazy `ForceRelocs` variable was only set when parsing assembly, so with a standard IR pipeline this is never set so relocations are never emitted. This update reverses this behaviour but keeps the lazy behaviour when parsing assembly when `-mattr=-relax` is used.
