Detect _savevr/_restvr + check in RELs
...
Some games include a copy of MW
runtime.c in RELs. Easy to check.
Some games also include _savevr/
_restvr for AltiVec. This is weird
but we can handle it as well.

Ensures that the analyzer won't
create a function when the target
is already contained within a
function. Useful with manual asm
that would otherwise trip up the
analyzer.

Support block_relocations and add_relocations in config.yml
...
This allows more granular control over generated relocations.
Also optimizes relocation address validity checks,
leading to ~20% faster relocation analysis.
Config example:
```
block_relocations:
# Block any relocation pointing to this address.
- target: .data:0x80130140
# Block any relocation originating from this address.
- source: .text:0x80047160
# (optional) End address to make it a range.
end: .text:0x800471A8
add_relocations:
# Inserts or overwrites a relocation.
# From: `subi r3, r3, 0x7657`
# To: `li r3, mesWInsert-0x1@sda21`
- source: .text:0x800473F4
type: sda21
target: mesWInsert
addend: -1

Add links field to config for overriding REL linkage
...
By default, every REL is linked with every other REL. Some games, like Mario Party, link RELs individually, so the module IDs are not unique. To support this, the `links` field can be used to override which _other_ modules are included in a module's analysis.
