The RISC-V port of binutils ld.bfd has a similar routine to change section sizes and update symbol values. @PkmX and I haven't implemented the relaxation in the lld RISC-V work. This patch inspires me to explore more on the possibility to implement section shrinking and make it general. I don't like the binutils implementation because it is quadratic about several variables.

Does that happen even in a middle of a basic block?
