Standardize the values for invalid and data opcodes (#261)
* Standardize the value for an invalid opcode

Also updated dependencies

[MIPS] Fix symbols being filtered out from target side of diff if target object contains .NON_MATCHING markers (#250)
* Fix filtering out symbols from the target side that have a symbol with the same name and a `.NON_MATCHING` suffix.

- Target side: Show all the symbols except the `.NON_MATCHING` ones.
- Base side: Ignore all the `.NON_MATCHING` symbols and also ignore the ones with the same name without the suffix

encoding difference.

Seeing how commonly used boricj's delinker extension is, it makes sense for this one to be included by default, before #238 is considered and worked on.

52c138bf06 Add "ignore_patterns" option to config
This allows explicitly ignoring changes to certain
files or directories, even if the changed file ends
up matching `watch_patterns`. The default value,
`build/**/*` will ensure that changes in the build
directory will not trigger a duplicate rebuild.

check for trailing nops (0x90). For PPC, check
for 4-byte 0x00 padding.

Fix data flow analysis for multiple text sections (#220)
* Fix data flow analysis for multiple text sections

* Data flow analysis results were only keyed by the symbol (function)
  address. That doen't work if there are multiple text sections, the
  result from the first function in one section will stomp the result
  from the first function in another because both have address zero.

* Remove the ambiguity by keying off of the section address as well.

* Formatting

* Satisfy wasm build

* Clippy

* Formatting again

* Thought that section was the section address not the section number.
