Fix Qt build in Linux, problem to recognize SDL2.
Update lang, adding Bulgarian
minor cleanup: No point in having special functions for ReadFCR/WriteFCR, they're smaller than many other ops..
Add udis86 b24baf1 (1.7.3?), not yet used.

Linked even on arm to avoid dependency complexity, might skip later.
Avoid some warnings in udis86.

These should all be safe.
Enable x86 disassembly in jit compare.
Avoid spinning the CPU in dev menu screens.
Merge pull request #6993 from unknownbrackets/udis86

Use udis86 as an x86 disassembler
Fix paths.

Hmm, this didn't happen when I added other things in ext... I blame 2013.
x86 Jit: Generate nicer code for some cases of addiu
Fix x86 disassembly in 32-bit mode
Sync x64 emitter to Dolphin's.
MIPSTables: Annotate fp and hi/lo in/out more accurately than just "other"

Some typo fixes
Merge x64 emitter from a newer Dolphin version.

This one can generate slightly smaller code by exploiting some EAX-only
encoding and various other short forms, and adds support for many newer
CPU instructions.
