SPU LLVM: Precompilation Improvements and misc fixes

[elad335]

• A fix for SPU fdunction discovery, do not count non-r0 link branches and branch-to-self or branch-to-next. A bit sad but this cuts found functions in TLoU from around 22xx to exacly 1800.
• Fix GOTO in the debugger in some conditions.
• Fix instriuction scrolling direction with the arrow keys in the debugger.
• Add CRC check to prevent use of invalid cache entries. (not perfect of-course)
• Add minimal discovery of tail-calls for precompilation.
• Revert a PPU Analyzer change, may address [Regression] God of War Ascension [BCES01741] crash after starting a New Game on a new profile (#14547) #14600.

You can just incorporate this entire check into section above

I have added some super-experiemental commits regarding SPU LLVM precompilation, now the count of functions should be about the same but it would take much more time to compile because it detects more instruction blocks.

When batch compiling cache: Most games freeze with spu runtime built the interpreter.

Methodology:

• 1st load: Create PPU/SPU cache ran, game booted afterwards, module count retrieved from the "Building SPU Cache..." dialog
• 2nd load: After playing the game for a short amount of time, restarting the game and retrieving module count from the "Building SPU Cache..." dialog

Game	1st load	2nd load
LOTR: Conquest	1269 modules	2953 modules

• LOTR: Conquest: One match of Instant action -> Black Gate -> Capture the flag

Also, I don't know if it's related to the PR or if the game just happened to glitch, but the AI felt very stupid, they weren't capturing their base point that was uncaptured plus one NPC got stuck without moving, there could be a SPU logic bug somewhere

What is actually counted in precompilation is functions not modules so it's a different thing, I may change the text later.
