…addend This is a regression that was introduced by encounter#158 diffing addends in addition to symbol names. But it's not really a bug in that PR, rather it seems like I simply never added the offset into the addend when creating a fake pool relocation for an extern symbol. So this commit fixes that root issue instead.

* PPC: Calculate pooled relocations Reimplements #140 The relocations are now generated when the object is first read in `parse`, right after the real relocations are read. `resolve_relocation` was changed to take `obj.symbols` instead of `obj` as an argument, because `obj` itself doesn't exist yet at the time the relocations are being read. * Improve readability of PPC pool relocs code * Fix regression causing extern pool relocs to be ignored * Fix showing incorrect diff when diffing weak stripped symbol with an addend This is a regression that was introduced by #158 diffing addends in addition to symbol names. But it's not really a bug in that PR, rather it seems like I simply never added the offset into the addend when creating a fake pool relocation for an extern symbol. So this commit fixes that root issue instead. * Add PPC "Calculate pooled data references" option * Fix objdiff-wasm compilation errors * Update PPC test snapshots

This is probably pretty rare and not that important, but I ran into a case where the (fake) relocation shown by objdiff had the correct symbol name but wrong addend, and objdiff wasn't highlighting it as a diff like it should be, so I implemented that. This also makes the func reloc diffing logic more similar to the data reloc diffing logic (which already checks addends).

Also the second commit is to make the addend be visually colored along with the symbol:
