Also updated dependencies

* OPCODE_DATA too

* 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

Luke Street 1e62d4664c Make function size inference logic arch-specific
For MIPS, account for delay slot nops. For x86,
check for trailing nops (0x90). For PPC, check
