Ryan Burns f58616b6dd Use symbol name when comparing against an externed reloc (#214)
* Use symbol name when comparing against an externed reloc

For partial matching files, often a symbol is externed even though it
should exist in the target object. We can still compare the symbol name,
instead of always returning a mismatch.

* Combine cases, and apply change reloc_eq in code.rs

Luke Street 07ef93f16a Ignore extern symbols with symbol name lookups
When searching for a symbol by name, only look at
symbols that are defined within the object,
ignoring extern symbols (symbols without section).

Luke Street e865f3d598 Fix symbol mapping mismatched match %
We have specific diff logic that relies on knowing
which object is the target object, and which is the
base. generate_mapping_symbols was designed in such
a way that it would reverse the target/base, leading
to a match percent shown that's different when it
gets applied.

Luke Street 0c48d711c7 Improve local branch relocation handling
Reworks the local-branch handling logic to be more
unified: scan_instructions does all the work up front,
and process_instruction / display_instruction can
simply use the calculated branch destination instead
of performing their own is-relocation-target-
function-local checks.

(Hopefully) Fixes #192

* Fix objdiff-wasm build

Data diffing doesn't seem to be fully implemented in objdiff-wasm yet, so just putting placeholders in so it compiles.

Luke Street 5898d7aebf Fix section ordering with many same-named sections
Before, this was comparing, for example, `.text-2`
with `.text-10` with standard string comparison,
yielding `.text-10` before `.text-2`.

Instead, this simply uses a stable sort by name,
which preserves the relative ordering of sections.

LagoLunatic cf5fc54cfa PPC: Reimplement pooled data reference calculation (#167)
* 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
