Mark Langen e638d0b17a Implementation of basic data flow analysis for PowerPC (#212)
* WIP implementation

* * Move flow analysis to dedicated file
* Show string constants inline
* Handle calls to MWCC "sled" helpers which otherwise disrupt flow analysis

* Run cargo insta review

* Apply clippy feedback

* Update more tests.

* Remove std use from ppc flow analysis

* Try to make wasm build work again

* More test changes

* Probably last wasm fix

* Formatting

* Fix WASM

* One more clippy thing

* Fixed display of float constants in a LFS or LFD instruction in case where there is a branch to the subsequent instruction with a different register value.

* On lines with a reloc, only hide Symbol type data flow values rather than all data flow values.

* Formatting

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

LagoLunatic 196c003a92 Reimplement colorized data relocation hover diffs (#182)
* Reimplement colorized data relocation hover diffs

* 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.

* Reloc hover: Add separators, override special color too

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 a1ea2919f8 Reimplement function data value tooltips, function data value diffing, and data relocation diffing (#166)
* Show data literal values on instruction hover

Reimplements #108

* Show reloc diffs in func view when data's content differs

Reimplements #153

* Data diff view: Show relocs on hover and in context menu

This reimplements #154

Note that colorizing the text depending on the kind of diff has still not been reimplemented yet

* Fix up some comments

Luke Street 741d93e211 Add symbol mapping feature (#118)
This allows users to "map" (or "link") symbols with different names so that they can be compared without having to update either the target or base objects. Symbol mappings are persisted in objdiff.json, so generators will need to ensure that they're preserved when updating. (Example: https://github.com/encounter/dtk-template/commit/d1334bb79e71af1a7b3b090bffda4adc483f722c)

Resolves #117
