[PATCH] D142777: [RISCV] Add asserts that we don't increase codesize during pseudo expansion

[Luís Marques via Phabricator via llvm-commits]

Overall seems a reasonable implementation, despite the limitations pointed out in the patch description.

BTW, a little while ago while debugging some branch relaxation issues I noticed that we were overestimating the size of some instructions and thus relaxing when it wasn't needed. I made a mental note to look into that when I could. It will be useful to have these additional checks if we start tightening loose upper bounds.
